EBook Description: Groups measure symmetry. No where is this more evident than in the study of symmetry in 2 and 3dimensional geometric figures. Symmetry, and hence groups, play a key role in the study of crystallography, elementary particle physics, coding theory, and the Rubik' s cube, to name just a few.
This is a book biased towards group theory not the 'the cube'. To paraphrase the German mathematician David Hilbert, the art of doing group theory is to pick a good example to learn from. The Rubik's cube will be our example. We motivate the study of groups by creating a grouptheoretical model of Rubik's cubelike puzzles. Although some solution strategies are discussed (for the Rubik's cube  the 3 x 3 x 3 and 4 x 4 x 4 versions, the 'Rubik tetrahedron' or pyraminx, the the 'Rubik dodecahedron', or megaminx, the skewb, square 1, the masterball, and the equator puzzle), these are viewed more abstractly than most other books on the subject. We regard a solution strategy merely as a nottooinefficient algorithm for producing all the elements in the associated group of moves.

Derivations of Applied Mathematics
This is a book of applied mathematical proofs. If you have seen a mathematical result, if you want to know why the result is so, you can look for the proof here.
The book's purpose is to convey the essential ideas underlying the derivations of a large number of mathematical results useful in the modeling of physical systems. To this end, the book emphasizes main threads of mathematical argument and the motivation underlying the main threads, deemphasizing formal mathematical rigor. It derives mathematical results from the purely applied perspective of the scientist and the engineer.
The Chaos Hypertextbook  Mathematics in the Age of the Computer
In the 1980s, strange new mathematical concepts burst forth from academic isolation to seize the attention of the public. Chaos. A fantastic notion. The study of the uncontainable, the unpredictable, the bizarre. Fractals. Curves and surfaces unlike anything ever seen in mathematics before. At first, one might think that these topics are beyond the comprehension of all but the smartest, most educated, and most specialized geniuses. It turned out that chaos, fractals, and the related topic of dimension are really not that difficult. One can devote an academic lifetime to them, of course, but the basic introduction presented in this book is no more difficult to understand than the straight line and the parabola.
Some of the topics discussed in this book have roots extending back to the close of the Nineteenth Century. But the really flashy stuff had to wait until integrated circuits integrated themselves into daily life. The real beauties of this concept are the colors, patterns, details, and motions at a level beyond line drawings on paper. This is when we need computers, lots of them, to reproduce every image, movie, and data set found in this book. This is mathematics in the age of the computer.
Unsolved Problems in Mathematical Systems and Control Theory
This book provides clear presentations of more than sixty important unsolved problems in mathematical systems and control theory. Each of the problems included here is proposed by a leading expert and set forth in an accessible manner. Covering a wide range of areas, the book will be an ideal reference for anyone interested in the latest developments in the field, including specialists in applied mathematics, engineering, and computer science.
The book consists of ten parts representing various problem areas, and each chapter sets forth a different problem presented by a researcher in the particular area and in the same way: description of the problem, motivation and history, available results, and bibliography. It aims not only to encourage work on the included problems but also to suggest new ones and generate fresh research. The reader will be able to submit solutions for possible inclusion on an online version of the book to be updated quarterly on the Princeton University Press website, and thus also be able to access solutions, updated information, and partial solutions as they are developed.
Basic Concepts of Mathematics
This book helps the student complete the transition from purely manipulative to rigorous mathematics. The clear exposition covers many topics that are assumed by later courses but are often not covered with any depth or organization: basic set theory, induction, quantifiers, functions and relations, equivalence relations, properties of the real numbers (including consequences of the completeness axiom), fields, and basic properties of ndimensional Euclidean spaces.
The many exercises and optional topics (isomorphism of complete ordered fields, construction of the real numbers through Dedekind cuts, introduction to normed linear spaces, etc.) allow the instructor to adapt this book to many environments and levels of students. Extensive hypertextual crossreferences and hyperlinked indexes of terms and notation add truly interactive elements to the text.
Linear Methods of Applied Mathematics
This is an online textbook written by Evans M. Harrell II and James V. Herod, both of Georgia Tech. It is suitable for a first course on partial differential equations, Fourier series and special functions, and integral equations. Readers are expected to have completed two years of calculus and an introduction to ordinary differential equations and vector spaces.
This text is suitable for students who are quite comfortable with calculus and are mainly interested in problem solving. For that reason, this text does not stress proofs, although it tries to give careful statements of theorems and to discuss the technical assumptions. Also, it does not spend much time with material like methods to calculate the integrals arising in Fourier analysis, choosing instead to appeal to software to do some calculations.
Abramowitz and Stegun: Handbook of Mathematical Functions
The present volume is an outgrowth of a Conference on Mathematical Tables held at Cambridge, Mass., on September 1516, 1954, under the auspices of the National Science Foundation and the Massachusetts Institute of Technology. The purpose of the meeting was to evaluate the need for mathematical tables in the light of the availability of large scale computing machines. It was the consensus of opinion that in spite of the increasing use of the new machines the basic need for tables would continue to exist.
Numerical tables of mathematical functions are in continual demand by scientists and engineers. A greater variety of functions and higher accuracy of tabulation are now required as a result of scientific advances and, especially, of the increasing use of automatic computers. In the latter connection, the tables serve mainly for preliminary surveys of problems before programming for machine operation. For those without easy access to machines, such tables are, of course, indispensable.
The Structure of Finite Algebras (Contemporary Mathematics)
The utility of congruence lattices in revealing the structure of general algebras has been recognized since Garrett Birkhoff's pioneering work in the 1930s and 1940s. However, the results presented in this book are of very recent origin: most of them were developed in 1983. The main discovery presented here is that the lattice of congruences of a finite algebra is deeply connected to the structure of that algebra. The theory reveals a sharp division of locally finite varieties of algebras into six interesting new families, each of which is characterized by the behavior of congruences in the algebras. The authors use the theory to derive many new results that will be of interest not only to universal algebraists, but to other algebraists as well.
The authors begin with a straightforward and complete development of basic tame congruence theory, a topic that offers great promise for a wide variety of investigations. They then move beyond the consideration of individual algebras to a study of locally finite varieties. A list of open problems closes the work.
A CookBook Of Mathematics
This textbook is based on an extended collection of handouts distributed to the graduate students in economics attending summer mathematics class at the Center for Economic Research and Graduate Education (CERGE) at Charles University in Prague.
There are two considerations needed to be taken in reading this book. First, this is a short textbook, which could be covered in the course of two months and which, in turn, covers the most significant issues of mathematical economics. This book attempts to maintain a balance between being overly detailed and overly schematic. Therefore this text should resemble (in the 'ideological' sense) a 'hybrid' of Chiang's classic textbook Fundamental Methods of Mathematical Economics and the comprehensive reference manual by Berck and Sydsaeter.
Elementary Mathematics
These are the first of two lecture notes used for Math130  Mathematics IE course at the Department of Mathematics, Macquarie University.
Mathematics IE is the standard entrylevel mathematics unit for students who have not had the benefit of a detailed introduction to the calculus that is equivalent to a reasonably high level of the NSW HSC Mathematics course. This unit then serves as a prerequisite for further study in mathematics. Taken by itself, it provides the basic mathematical knowledge required by students in other disciplines.
