Colloquium 02/15: Dr. Tracy Weyand of Baylor University on "The Spectra of the Magnetic Schrodinger Operator on Graphs"

On Monday, February 15, at 3:30 PM in Math 357, Dr. Tracy Weyand of Baylor University will be talking about “The Spectra of the Magnetic Schrodinger Operator on Graphs.”

Abstract:
In the most general sense, a graph represents a relationship between a set of objects. Applications appear in chemistry, physics, engineering, computer science, and social science to name a few. In most applications, the relationship between objects (vertices) is represented by an operator that acts on functions whose domain is the graph. My research focuses on studying the spectra and corresponding eigenfunctions of such operators.

Throughout this talk, we will consider two types of graphs: discrete and metric. Eigenvalues of the magnetic Schrodinger operator on both types of graphs can be considered functions of the magnetic flux on the graph. Viewing the eigenvalues as functions, we have been able to determine their Morse index (a measure of stability). This result has led to progress on several other problems including the inverse problem (information the eigenvalues provide about the structure of a graph) and the location of Dirac cones (touching points) in the spectral bands (as well as properties of the corresponding eigenfunctions there).

About Us

The Department of Mathematics and Statistics is a friendly and supportive place for our students. Our faculty are committed to excellence and continual improvement in teaching and advising students through our challenging curriculum:

Our math clubs are very active in hosting math talks and participating in conferences, fundraisers, and social activities.

We offer one of the leading certification programs in the state in mathematics teaching. The department proudly produces qualified teachers at all levels.

We offer dual-credit coures to local and rural schools and make visits to speak about mathematics and statistics.

Why study mathematics?

Mathematics is perhaps the most intellectually challenging and practical major you can choose. Some major in math for the enjoyment and beauty of the subject. Others major in math for its practicality and applicability to the sciences, engineering, finance, and even the social sciences. Mathematics develops rigorous analytical thinking skills that are prized in all fields of human endeavor.

Mission Statement

The purpose of the Department of Mathematics and Statistics is to attract and retain the best available scholars who actively pursue knowledge of mathematics, statistics, and/or mathematics education and who skillfully communicate their knowledge of the subject to their students, colleagues, and the community as a whole.

Specific roles of the Department are:

  1. To provide a sound curriculum for students who wish to pursue a career in mathematics or statistics in business and industry;
  2. To provide service courses for students who are majoring in some other department, but who need mathematics or statistics as a tool or to satisfy general degree requirements;
  3. To offer preparation to those who are planning to pursue a graduate degree;
  4. To prepare teachers for positions in colleges, universities, and public or private schools.
