"This book deals with the question on how NX(p), the number of solutions of mod p congruences, varies with p when the family (X) of polynomial equations is fixed. While such a general question cannot have a complete answer, it offers a good occasion for reviewing various techniques in l-acic cohomology and group representations, presented in a context that is appealing to specialists in number theory and algebraic geometry"--Provided by publisher.
