In this talk, we will share early findings from an NSF study of 75 doctoral students and recent PhDs in mathematics from underrepresented groups. The project has conducted in-depth, semi-structured interviews with four cohorts: newly accepted students, early graduate students …
Presented by Prof. Qingshuo Song, associate professor at Worcester Polytechnic Institute. In this talk, we will discuss the asymptotic behavior of the solution to a linear-quadratic stochastic optimal control problems. By establishing a connection between the ergodic cost problem and …
Presented by Dr. Daniel Stoertz, Visiting Assistant Professor of Mathematics at St. Olaf College. In Complex Dynamics, we study the iteration of holomorphic or meromorphic functions on the complex plane or the Riemann sphere. Of particular interest is the behavior …
The goal of this talk is to study a fourth-order nonlinear parabolic system with dispersion for describing bacterial aggregation. Analytical solution of traveling wave is found by taking into account the dispersion coefficient. Numerically, we demonstrate that the initial concentration …
Department of Mathematical Sciences Colloquium presented by Dr. Selvi Kara, Bryn Mawr College. One of the central problems in commutative algebra concerns understanding the structure of an ideal in a polynomial ring. Abstractly, an ideal’s structure can be expressed through …
Department of Mathematical Sciences Colloquium presented by Bart Adrian, UWM. Atmospheric science provides excellent opportunities for encouraging student interest in all fields of STEM (Science, Technology, Engineering, Math). A model outreach program (“Chasing the Wind: Tools for Understanding the Weather”) …
Department of Mathematical Sciences Colloquium presented by Dr. Bogdan Nica, Indiana University-Purdue University Indianapolis. Matrices of determinant 1 can be reduced to the identity matrix by row- and column-operations. This is a well-known fact of linear algebra--assuming that we work …
Presented by Dr. Michael Dairyko, Director of Ticketing Analytics, Milwaukee Bucks. Data science is a continuously evolving field that lives at the intersection of mathematics, statistics, and computer science. Many industries have started to utilize data science to extract valuable …
In group theory, any group can be defined by specifying generators and relations. But for infinite groups, when trying to define a model for a generic/random group, there are many options for how to vary these generators and relations. We …
Presented by Dr. Michael Young, Associate Professor of Mathematics, Carnegie Mellon University. A set is considered rainbow if each element of the set is assigned a distinct color. In this talk, we will discuss problems and techniques about determining the …
Dr. Laura Colmenarejo, Professor of Mathematics, North Carolina State University. In algebraic combinatorics, the Robinson-Schensted-Knuth algorithm is a fundamental correspondence between words and pairs of semistandard tableaux illustrating identities of dimensions of irreducible representations of several groups. In this talk, …
Presented by Dr. Mark Colarusso, Professor of Mathematics, University of South Alabama. In the 19th century, physicists were interested in determining the conditions under which the equations of motion for a classical mechanical system could be found by integrating a …
If G is a Lie group, let Sub(G) be the set of all subgroups H of G that are topologically closed subsets of G. There is a natural topology on Sub(G), called the Chabauty topology. We’ll define the Chabauty topology, …
Presented by Dr. Erik Insko, Professor of Mathematics, Iowa State University. In this talk, I will give a brief introduction to Ehrhart polynomials, which count the number of lattice points in a convex lattice polytope and also describe the polytope's …
Presented by Dr. Steve Butler, Professor of Mathematics, Iowa State University. A classic problem in mathematics is "Can you hear the shape of a drum?" In graph theory, this is often phrased in terms of the eigenvalues of matrices associated …
