Book Recommendations
These are semi-official #math book recommendations for various topics. These are all personal recommendations of channel regulars. This means that given the collective experience of the channel, these are the books to read. We made an arbitrary split between the mathematics before and after calculus. All of the former will be found in Pre-College Mathematics section. All of the latter will be found each under its own subject listing. We also have a section devoted to books of general interest.
| Table of contents |
General Interest
These books are intended for a general audience. history/philosophy of math, 'how to solve it'
The History of Calculus and Its Conceptual Development (http://www.amazon.com/gp/product/0486605094/) by Boyer
A History of Mathematics (http://www.amazon.com/gp/product/0471543977/) by Boyer
A Mathematician's Apology (http://www.amazon.com/gp/product/0521427061/) by Hardy
Pre-College Mathematics
This category is the catch-all for topics generally preceding calculus. This includes high school algebra, geometry and trigonometry. Unfortunately decent books are hard to find. The recommendations here are not as personal and less authoritative than the others. They are made to be helpful, but should be taken with a grain of salt.
Schaum's outlines -- I used various ones for college-level math and they were useful, and the calculus one below is well-recommended. But some are good; some are bad.
- Algebra the Easy Way (http://www.amazon.com/gp/product/0764119729/) by Downing
- Geometry the Easy Way (http://www.amazon.com/gp/product/0764101102/) by Leff
- Trigonometry the Easy Way (http://www.amazon.com/gp/product/0764113607/) by Downing
- Precalculus the Easy Way (http://www.amazon.com/gp/product/0764128922/) by Leff
The book Calculus the Easy Way (http://www.amazon.com/gp/product/0812091418/) by Downing is an easy and intuitive introduction to calculus. It is on this basis (and only this basis) that I recommend the other books in the series.
Algebra
In course titles, often called "abstract" or "modern" algebra to distinguish it from high school algebra, but known simply as algebra otherwise, this subject analyzes groups, rings, and fields. These are all algebraic structures but with sometimes subtly different properties. See also: commutative algebra, linear algebra, representation theory.
Abstract Algebra (http://www.amazon.com/gp/product/0471368571/) by Dummit and Foote
Groups and Representations (http://www.amazon.com/gp/product/0387945261/) by Alperin and Bell

Topics in Algebra (http://www.amazon.com/Topics-Algebra-I-N-Herstein/dp/0471010901/ref=sr_1_1?ie=UTF8&s=books&qid=1272768920&sr=1-1) by Herstein
A quote from Gallian's book states "A whole generation of textbooks and an entire generation of mathematicians, myself included, have been profoundly influenced by that text" - Georgia Benkart. Also see Abstract Algebra by the same author for a lower level treatment.
A first Course in Abstract Algebra (http:// www.amazon.com/First-Course-Abstract-Algebra-7th/dp/0201763907/ ref=sr_1_1?ie=UTF8&s=books&qid=1272769054&sr=1-1) by Fraleigh
A good introduction to abstract algebra. More gentle than Herstein.
Contemporary Abstract Algebra (http:// www.amazon.com/Contemporary-Abstract-Algebra-Joseph-Gallian/dp/ 0547165099/ref=sr_1_2?ie=UTF8&s=books&qid=1272769054&sr=1-2) by Gallian
Another introduction to abstract algebra. Similar to Fraleigh, but with some topic reorderings. Many problems and hints in back of text. Many biographies of mathematicians, some GAP usage.
A first Course in Abstract Algebra with Applications (http:// www.amazon.com/First-Course-Abstract-Algebra-3rd/dp/0131862677/ ref=sr_1_1?ie=UTF8&s=books&qid=1272769173&sr=1-1) by Rotman
A introductory abstract algebra text. The ordering is more awkward than the prior texts, but sections are fairly well written.
Algebra (http://www.amazon.com/Algebra-Michael-Artin/dp/0130047635/ref=sr_1_1?ie=UTF8&s=books&qid=1272769272&sr=1-1) by Artin
Algebraic Geometry
Classically, algebraic geometry was the study of polynomials, and more importantly the geometry of their solution sets. In modern times, while this statement remains true, the tremendous technical power of the methods of modern algebraic geometry (ex: sheaves, cohomology, stacks, Grothendieck topologies, etc) has ensured that the influence of algebraic geometry on other subjects in mathematics (notably number theory, algebraic topology and representation theory) is impossible to overestimate.
A few introductory books on algebraic geometry are:
Algebraic Geometry: A First Course (http://www.amazon.com/gp/product/0387977163/) by Harris
Undergraduate Algebraic Geometry (http://www.amazon.com/gp/product/0521356628/) by Reid
A basic treatment of scheme theory and (Zariski) sheaf cohomology can be found in:
EGA (http://cohomology.princeton.edu/books/Math/EGA_SGA/EGA/) by Grothendieck
Algebraic Geometry (http://www.amazon.com/gp/product/0387902449) by Hartshorne
Algebraic Geometry and Arithmetic Curves (http://www.amazon.com/gp/product/0198502842) by Liu
Many important results of Grothendieck, besides those in EGA, can be found in SGA (http://cohomology.princeton.edu/books/Math/EGA_SGA/SGA/).
Mumford's Abelian Varieties (http://www.amazon.com/gp/product/0195605284) is perhaps the most beautiful text on varieties which are the algebraic analogue of the Lie groups of differential geometry. It does, however, lack arithmetic applications as it always works over algebraically closed based fields.
Champs Algebrique (http://www.amazon.com/gp/product/3540657614/) by Laumon and Morret-Baily (LMB) is the canonical reference when it comes to the theory of algebraic stacks (which originates in the seminal paper (http://www.numdam.org/numdam-bin/item?id=PMIHES_1969__36__75_0) of Deligne and Mumford, two Fields medallists). However, if you're not a Fields medallist, the french book is an incredibly hard read. Fortunately, many people who wish to learn about stacks are not Fields medallists and are extremely good expositors. So there are plenty of places on the web where you can find a basic readable introduction to the theory of stacks, such as this (http://arxiv.org/abs/math/0412512) one. One must keep in mind, however, that these are only introductions and that LMB still remains the standard reference. If, on the other hand, you find that LMB is not general enough or if you're more categorically inclined, Giraud's book (``Cohomologie non-abelienne"), which talks in depth about fibered categories and stacks (but not *algebraic* stacks), might be worth a look.
Claire Voisin's new books (1 (http://www.amazon.com/gp/product/052180260) and 2 (http://www.amazon.com/gp/product/0521802830)) beautifully exhibit the applications of algebraic geometry to differential and complex geometry. It is only a matter of time before these books take their place besides Griffiths' and Harris' beautiful text (http://www.amazon.com/gp/product/0471050598/) as the standard references for complex algebraic geometry.
For those interested in arithmetic applications, there's no shortage of good books either. Silverman's twins (1 (http://www.amazon.com/gp/product/0387962034) and 2 (http://www.amazon.com/gp/product/0387943285)) are wonderfully readable introductions to the arithmetic theory of elliptic curves, especially since they avoid the high-brow methods of the theory of abelian varieties when possible, thereby making the subject more accessible. The proceedings (http://www.amazon.com/gp/product/0387963111) of the conference that followed Faltings' stunning proof of the Mordell conjecture are full of beautiful surveys on various topics of interest to arithmetic geometers, even those who don't care about Faltings' proof. The Neron models book (http://www.amazon.com/gp/product/0387505873) too is full of expositions on various topics of interest to arithmetic geometers.
Grothendieck dreamt of a world of motives in the 60s and, almost half a century later, we're still trying to realise this dream. An extremely nice summary of the progress in this direction, up until the mid 90's, can be found in the twin-volume Seattle conference proceedings (http://www.ams.org/bookstore-getitem/item=pspum-55.s). The articles in these proceedings are, generally, very well-written and, as such, provide concise introductions to various subjects and, consequently, might be helpful to even those with no direct interest in motives. In the subsequent years, Voevodsky has come up (http:// www.amazon.com/Cycles-Transfers-Motivic-Homology-Theories/dp/0691048150/ sr=8-1/qid=1161626911/ref=sr_1_1/002-2929973-5413605?ie=UTF8&s=books) with a conjectural motivic cohomology theory which has already found spectacular applications (ex: the Milnor conjecture)
This (http://www.amazon.com/gp/product/082183424X)
recently published (bilingual) book contains numerous letters that
Serre and Grothendieck, two of the founding fathers of modern algebraic
geometry, exchanged in the earlier part of the second half of the
twentieth century. For a student of modern algebraic geometry, reading
these letters can be a highly rewarding experience on many counts.
Firstly, they expose the mistakes these awe-inspiringly smart
mathematicians made, thereby making them more human. Secondly, they
beautifully elucidate how many of the great ideas in algebraic geometry
(ex: motives) originated. Lastly, they also help eliminate the
misconeption that mathematicians do all their work alone (stuck up in
attic, sometimes!); indeed, these letters are one of the best examples
of the kind of collaboration that takes place at the highest level of
the subject. All in all, a wonderful read for anyone with more than a
passing interest in algebraic geometry.

A higher level text than Haberman.
Differential Topology
Differential topology is the natural generalization of calculus of many variables. Calculus being essentially local, the object of study in differential topology — known as a manifold — locally acts and feels like ordinary Euclidean space. As such, one can study manifolds and functions on them in a manner very similar to the way one does in multivariable calculus. One can speak of derivatives and integrals, use conditions on the derivative to determine extrema, and much more... That being said, there are global properties of manifolds that are beyond what ordinary calculus can see.
