25th Isidore and Hilda Dressler Lecture today

By Reta McDermott

The mathematics department presents the 25th Isidore and Hilda Dressler Lecture. Roger Baker from Brigham Young University will present "Sieves In Number Theory" at 2:30 p.m. Thursday, April 25, in 102 Cardwell Hall. 

The lecture abstract:

The speaker describes how sieve methods impact number theory, with particular reference to two of his favorite problems: Finding primes in short intervals [x,x+y] where y is a relatively small power of x, and finding primes in a Piatetski-Shapiro sequence where the nth term is the integer part of a fixed non-integer power of n. The talk will be accessible to graduate students who are not necessarily specializing in number theory.
