A graduate textbook devoted entirely to integer-valued polynomials on the ring of integers, which have long been known and used in calculus. Discusses coefficients and values, additive structure, polynomials on a subset, prime ideals, multiplicative properties, derivatives and finite differences, rational functions, polynomials in several indeterminates, and other aspects. About 30 exercises accompany each chapter. Member prices are $45 for individual and $60 for institutions. Annotation c. by Book News, Inc., Portland, Or.
