Seminars

Algebra Seminar:   Monday, April 21, 2:00-2:50 p.m. in DU 428
Speaker: John Beachy
Topic: Prime "Ideals" for Modules
Abstract: An R-module M plays the same role in the category sigma[M] as does R in the category R-Mod. Is there a useful analog (for M) of the notion of a prime ideal of R?

Complex Analysis Seminar:   Monday, April 21, 2:00-2:50 p.m. in DU 428
Speaker: Linda Sons
Topic: Derivatives Bounded on Preimages of Unbounded Sets, continued
Abstract: If f is a transcendental entire function and M is an unbounded set in the complex plane, it is known that the first derivative of f on the set of preimages of M is unbounded. We will discuss what is known when the first derivative is replaced by the second or higher.
