Mon September 28, 2015, 5 PM, Van Vleck 901

Math Club is having its first meeting of the Fall 2015 semester on Monday, September 28 at 5:00 pm! We will meet in 901 Van Vleck for a talk by Professor Paul Terwilliger on tridiagonal matrices. You can find more information on the talk below.

We will also be asking for interest in running for positions for math club. This year, we will be looking for two coordinators, a social chair, a PR chair, and a treasurer. If you are interested in helping the math club in one of these positions, let us know at our meeting. If you have a conflict this Monday, but are still interested in helping out, please e-mail thameister@wisc.edu for more information.

If you are interested in meeting other students interested in math or in learning new or exciting math, please come to see what our club is all about!!

Title: Finding the eigenvalues of some tridiagonal matrices using hidden symmetry.

Speaker: Paul Terwilliger

Abstract: A square matrix is called tridiagonal whenever each nonzero entry is on the main diagonal, the superdiagonal, or the subdiagonal. Tridiagonal matrices come up naturally in Combinatorics, Orthogonal polynomials, Representation theory, and more. We present an attractive family of tridiagonal matrices, and show how they possess symmetry that is not readily apparent. We use this hidden symmetry to compute the eigenvalues of these matrices.
