Algebra Seminar:   Monday, March 31, 2:00-2:50 p.m. in DU 428
Speaker: Caroline Kettlestrings
Topic: Classifying Class Three Nilpotent Table Algebras of Order p^3
Abstract: In a previous algebra seminar, I presented an argument showing that, except for distinguishing isomorphism classes, the problem of classifying the class three nilpotent standard integral table algebras of order p^3 for a prime p reduced to solving a certain system of equations in p variables. Those equations can be solved using a combination of number theory and linear algebra. I will present an outline of the argument that solves the system.

Complex Analysis Seminar:   Monday, April 14, 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.
