About the Authors 459

pXIII - First courses in abstract algebra usually cover number theory, groups, and commutative rings - first encounter with groups inadequate, we focus on number theory, polynomials, commutative rings - introduce groups in last chapter, earlier discussion of commutative rings allows explaining how groups are used to prove Abel's Theorem: there is no generalization of the quadratic, cubic, and quartic formulas giving the roots of the general quintic polynomial - proposal: undergraduate abstract algebra should be a sequence of two courses, with number theory and commutative rings in the first course, and groups and linear algebra (with scalars in arbitrary fields) in the second - natural direction for us is towards algebraic number theory, whereas the usual direction is towards Galois theory - 4000 years ago led to Pythagorean triples: positive integers a; b; c satisfying a^{2} + b^{2} = c^{2} - 2000 years ago all triplets found - Pierre de Fermat (between 31.10. and 6.12.1607 – 12.1.1665 France) searched for positive integer solutions to a^{n} + b^{n} = c^{n} for n > 2 --- called Fermat’s Last Theorem - end of 20^{th} century, Andrew Wiles (11.4.1953 Cambridge, England) proved Fermat’s Last Theorem in 1995 (Guinness Book of World Records as the "most difficult mathematical problem" - Wiles recieved Norwegian Abel prize worth €600,000)

pIX - before solution challenge to mathematicians as climbing Mount Everest - number theory recorded in Euclid has similarities with behavior of polynomials, generalizations of prime numbers and unique factorization owe their initial study to attempts at proving Fermat’s Last Theorem - abstract algebra is not merely beautiful and interesting, but also a valuable, perhaps essential, topic for understanding high school mathematics

Some features of the book:

... connections ... sidenotes ... interspersed in the text are boxed “callouts” such as How to Think About It ... Historical Note ... - biographies based on www-history.mcs.st-andrews.ac.uk - Etymology traces out the origin of some mathematical terms - often helps to understand the ideas they name - example:

pXV - Etymology. The word mathematics comes from classical Greek; it means “knowledge,” “something learned.” But in ancient Rome through the thirteenth century, it meant “astronomy” and “astrology.” From the Middle Ages, it acquired its present meaning.

The word arithmetic comes from the Greek word meaning “the art of counting.”

The word geometry, in classical Greek, meant “science of measuring;” it arose from an earlier term meaning “land survey.”

acknowledgements ... - Keith Conrad's website

A Note to Students:

work through as many exercises as possible, especially those that appear difficult - quite often, you will learn something valuable even if you don’t solve it completely -

two special kinds of exercises:

• labeled Preview may seem to have little to do with the section at hand; they are designed to foreshadow upcoming topics, often with numerical experiments

• labeled Take it Further develop interesting ideas that are connected to the main themes of the text, but are somewhat off the beaten path - not essential for understanding what comes later in the text

- exercise marked with asterisk, such as 1.8*, means that it is either used in some proof or it is referred to elsewhere in the text. For ease of finding such exercises, all references to them have the form “Exercise 1.8 on page 6” giving both its number and the number of the page on which it occurs

A Note to Instructors:

We recommend giving reading assignments to preview upcoming material - this contributes to balancing experience and formality as described above, and it saves time - many important pages can be read and understood by students, and they should be discussed in class only if students ask questions about them - possible to use book as text for three hour one-semester course, but we strongly recommend that it be taught four hours per week

Foreword

pV - It seems to me far more interesting and profitable in an introductory study of modern algebra to carry a few topics to a significant depth ... firmly based on the historical development of the subject - book only three areas: group theory, Galois theory, and classical ideal theory - in each case there is more depth and detail - all three topics converge in the fundamental theorem of algebraic number theory for Galois extensions of the rational field, the final result of the book

I.1 What Is Mathematics About?

1 Algebra, Geometry, and Analysis

1.1 Algebra versus Geometry

p1 - high school pupils think of algebra: substitute letters for numbers, geometry as shapes (circle, triangle, cube, sphere etc.) and concepts (rotation, reflection, symmetry etc.) -

p2 contrasted with arithmetic, more direct study of numbers themselves - contrast not in advanced math - geometrical problems may be converted into algebra etc., Cartesian coordinates - example circle rotation, visualization or algebraic approach, matrices etc. - while one can distinct between algebra and geometry, but shouldn't imagine boundary between the two is sharply defined - branch called algebraic geometry (1V.4) - different mehtods of thinking: algebra more symbolic, geometry more pictorial -> influence which subjects mathematician chooses to pursue

1.2 Algebra versus Analysis

... not branches should be classified into algebra or analysis, but mathematical techniques - derivative of x^{3} is 3x^{2} - gradient at x is 3x^{2}

p3 - a proof that x^{4} − x^{2} − 6x + 10 is positive for every real number x - ... proof ... - algebraic equivalent: (x^{2} − 1)^{2} + (x − 3)^{2} - ... - 1 analysis often involves limiting processes and algebra usually does not - 2 algebraists like to work with exact formulas and analysts use estimates - 3 algebraists like equalities and analysts like inequalities

2 The Main Branches of Mathematics

potential confusion: words “algebra,” “geometry,” and “analysis” refer *both* to specific branches of mathematics *and* to ways of thinking that cut across many different branches - keep in mind distinctions of previous section and be aware that they are in some ways more fundamental

On Numbers and Games

pV - based on course at Stanford University (California) since 1970 - CM born in dark and stormy decade - Knuth missed math tools, created this course - CM was antidote to Abstract Math (concrete classical results wiped out by New Math) -

pVI - CM blend of CONtinuous and disCRETE math - controlled manipulation of math formulas, using collection of techniques for solving problems - if material of book is learned, reader will solve everything only on paper with handwriting! - major topics treated in this book include sums, recurrences, elementary number theory, binomial coefficients, generating functions, discrete probability, and asymptotic methods - will become familiar with discrete math as student of calculus with continuous operations (like absolute-value function and infinite integration) - original course textbook was "Mathematical Preliminaries" from TAOCP - 110 pages quite terse, OP (author) drafted supplementary notes, this book is outgrowth -

pVII - book is kind of manifesto about our (authors) favorite way to do mathematics, turned out to be a tale of mathematical beauty and surprise - we think math is not cold and dry, but fun, no line between work and play needed - margins include direct quotations from famous mathematicians, actual words in which they announced some of their fundamental discoveries -

pVIII - more than 500 exercises in six catgories: warmups, basics, homework exercises, exam problems, bonus problems - research problems - answers in Appendix A - math typeface by Hermann Zapf, like handwriting, called AMS Euler - Concrete mathematics is Eulerian mathematics -

pIX - Thanks to: ... 16 years' lecture notes - notes to 2nd edition ... - $ 2.56 for mistakes

pX - notation of symbols and pages where they are explained:

`lnx --- lgx --- log x --- ⌊x⌋ --- ⌈x⌉ --- x mod y --- {x} --- ∫f(x) δx ---`

pXII-XIII - Contents - 1 Recurrent Problems (p1=20p) - 2 Sums (p21=45p) - 3 Integer Functions (p67=34p) -

∫^{b}_{a}f(x) δx --- x^{n} --- x^{n} --- n¡(! usidedown) --- Rz --- Iz --- H_{n} --- H_{n}^{(x)} ---

pXI - f^{(m)}(z) --- [n(/)m] --- {n(/)m} --- <n(/)m> --- <<n(/)m>> --- (a_{m}, ...,a_{0})_{b} ---

K(a_{1},...,a_{n}) --- F(^{a,b}(/)_{c}|z) --- #A --- [zn] f(z) --- [α..β] --- [m=n] --- [m\n] ---

[ m\\n ] --- [m⊥n] ---

--- '...' for written, "..." for spoken text, string of 'string' is called "string" -

expression 'a/bc' is same as 'a/(bc)' --- log x/log y = (log x)/(log y) --- 2n! = 2(n!)

p1 - chapter 3 sample problems - all investigated repeatedly by mathematicians, solutions use recurrence, depending on solutions to smaller instances

1.1 The tower of Hanoi - invented by French math. Edouard Lucas 1883 (bk260) - tower of 8 disks, stacked in decreasing size on one of three pegs - transfer entire tower to one of the other pegs, moving only one disc at a time, never moving larger one onto smaller - Lucas furnishes to tower of Brahma, 64 disks of gold on 3 diamond needles, God asks at beginning of time priests to transfer according to same rules above, priests work day and night, when finish tower will crumble and world will end -

p2 - best to do: how many moves necessary and sufficient to perform task - best way to tackle a question like this is to generalize it: Brahma tower 64 discs, Hanoi 8 - consider n discs - we'll see repeatedly in book: it's advantageous to "look at small cases" first - easy transfer tower of 1 ore 2 discs, then 3, and 0 - next step introduce appropriate notation: name and conquer - T_{n} is minimum number of moves to transfer n disks according to rules - then T_{1} = 1, T_{2} = 3, (T_{3} = 7 etc.) - T_{0} = 0 is smallest case - now think big:

1 - The Foundations: Logic and Proofs

1.1 - Propositional Logic

p1 - examples ...

p3 - proposition p (or q, r, s ...) is T (true) or F (false) - ¬p is negation of p, read "not p" - Def 1: if p T, then ¬p F --- if p F, then ¬p T --- logical operators are called "connectives"

p4 - Def 2: if p and q are T, the conjunction ∧ of p and q, p ∧ q, is also T, otherwise F - in conjunctions sometimes "but" is uses instead of "and": The sun is shining, but it is raining

`Def 3: disjunction ∨ (read or) is true if p or q are true, or both,`

p ∧ q has 4 possible results: TFFF - p ∨ q has 4 possible results: TTTF

but false if both are false --- p ∨ q

Notation

& denotes conjunction, pronounced and

~ denotes negation, pronounced not

Boldface A and E used to denote the universal and existential quantifiers

In the following formulas, the left part is the notation used and defined here in terms of the right part. Note that the left parts avoid the use of the symbol "...", which appeals to the readers intuition.

`Ai: m ≤ i < n : P`

The P_{i} ≡ P_{m} & P_{m+1} & ... & P_{n-1}_{i} are predicates, and the formula asserts that for all indices i ranging from a given value m to, but excluding a value n, P_{i} holds.
`Ei: m ≤ i < n : P`

The P_{i} ≡ P_{m} or P_{m+1} or ... or P_{n-1}_{i} are predicates, and the formula asserts that for some indices i ranging from a given value m to, but excluding a value n, P_{i} holds.
`MIN i: m ≤ i < n : x`

_{i} = minimum(x_{m}, ... , x_{n-1)}`MAX i: m ≤ i < n : x`

_{i} = maximum(x_{m}, ... , x_{n-1)}
