The Department of Mathematics sponsors a regular colloquium that hosts several talks by
external speakers every year and a general faculty seminar for talks by faculty and
students. Seminars are listed below after the colloquia.
On Friday, May 5, 2023, Dr. Sergiy Borodachov, Professor of Mathematics at Towson University, will present a sabbatical lecture on Orthogonal Polynomials and Potentials of Spherical Designs. The lecture will take place at 2 pm in 7800 York Road, Room 205.
Abstract: We will discuss results on universal minima and maxima of potentials of spherical point configurations that form nodes of cubature formulas of the highest algebraic degree of precision. Properties of Gegenbauer and Jacobi orthogonal polynomials are an important tool in analyzing their potentials and establishing sharp upper and lower bounds. Our results apply to many known regular spherical configurations in various dimensions. This research is related to approximation theory, discrete geometry, theory of spherical designs, and potential theory. We will also talk about our work on construction of the pointwise optimal recovery algorithm for twice differentiable functions on a rectangular box with uniformly bounded second order derivatives in any direction. The data is given by values and gradients of a function at a fixed rectangular grid. Other activities from our sabbatical plan will be also mentioned.

The Mathematics Seminar is the venue where Towson faculty and students report on their research activities. The Graduate Seminar hosts expository talks by faculty that introduce graduate students in the departmental APIM Master's program to topics that present opportunities for graduate research projects.
