Colloquium 10/24: Dr. Brandy Doleshal on "Dehn Surgery and Knots in the Genus 2 Surface"

On Monday, October 24, at 3:30 pm in Math Building 357, Dr. Brandy Doleshal will be talking about "Dehn Surgery and Knots in the Genus 2 Surface."

Abstract: Low-dimensional topology is the study of 3- and 4-manifolds. A link is an embedding of some number of circles into a 3-manifold M. Each circle is called a component, and a link of one component is called a knot. Dehn surgery is a way of replacing a neighborhood of a component of knot or link to create a (possibly) new manifold. A classical result of Wallace and Lickorish tells us that any closed compact 3-manifold can be obtained by Dehn surgery on a link. Hence we can study 3-manifolds through studying knots and links. We will discuss some knots on the genus 2 surface and the Dehn surgeries they admit. (flyer in PDF form)

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.
