Algebraic Topology - Bray, Clark

. .

Résumé :
Algebraic Topology is an introductory textbook based on a class for advanced high-school students at the Stanford University Mathematics Camp (SUMaC) that the authors have taught for many years. Each chapter, or lecture, corresponds to one day of class at SUMaC. The book begins with the preliminaries needed for the formal definition of a surface. Other topics covered in the book include the classification of surfaces, group theory, the fundamental group, and homology. This book assumes no background in abstract algebra or real analysis, and the material from those subjects is presented as needed in the text. This makes the book readable to undergraduates or high-school students who do not have the background typically assumed in an algebraic topology book or class. The book contains many examples and exercises, allowing it to be used for both self-study and for an introductory undergraduate topology course....

Biographie:

Clark Bray?is an Associate Professor of the Practice?in the Department of Mathematics at Duke University. He graduated from Rice University in 1993, cum laude, with majors in Mathematics and Physics, and finished his Ph.D. in Mathematics at Stanford University in 1999, studying algebraic topology with Professor Gunnar Carlsson. While subsequently a Lecturer at Stanford, he created and taught a program in algebraic topology for talented high school math students at the Stanford University Mathematics Camp (SUMaC) in 2001-2003.?

Simon Rubinstein-Salzedo ?received his PhD in mathematics from Stanford University in 2012. Afterwards, he taught at Dartmouth College and Stanford University. In 2015, he founded Euler Circle, a mathematics institute in the San Francisco Bay Area, dedicated to teaching college-level mathematics classes to advanced high-school students, as well as mentoring them on mathematics research. His research interests include number theory, algebraic geometry, combinatorics, probability, and game theory.
