Math Talks for Undergraduates

For many years Serge Lang has given talks to undergraduates on selecte d items in mathematics which could be extracted at a level understanda ble by students who have had calculus. Written in a conversational to ne, Lang now presents a collection of those talks as a book. The talks could be given by faculty, but even better, they may be given by stud ents in seminars run by the students themselves. Undergraduates, and e ven some high school students, will enjoy the talks which cover prime numbers, the abc conjecture, approximation theorems of analysis, the s emi-parallelogram law and Bruhat-Tits spaces, harmonic and symmetric p olynomials, and more in a lively and informal style.
