What We Still Don't Know About Addition and Multiplication

April 7, 2014 8:00 PM – 9:00 PM

Searles Science Building, Room 315

How could there be something we don't know about arithmetic? It would seem that subject was sewn up in third grade. But here's a problem we don't know: What is the most efficient method for multiplication? Another: How many different numbers appear in a large multiplication table? Come hear about many more of these types of problems, plus some recent progress.

Carl Pomerance will present the Dan E. Christie Mathematics Lecture sponsored by the Mathematics Department.

Professor Pomerance received his B.A. from Brown University in 1966 and his Ph.D. from Harvard University in 1972 under the direction of John Tate. Currently he is the John G. Kemeny Parents Professor of Mathematics at Dartmouth College, after previous positions at the University of Georgia and Bell Labs. A number theorist, Pomerance specializes in analytic, combinatorial, and computational number theory, with applications in the field of cryptology. He considers the late Paul Erdos as his greatest influence.
