The UK College of Arts and Sciences would like to congratulate Dr. Nathan Druivenga, arecipient of the A&S Outstanding Teacher Award! Druivenga is a lecturer for the Mathematics Department at the University of Kentucky. Since beginning his teaching career at UK in 2016, he maintains a large focus on teaching introductory-level math courses. Druivenga received his master’s degree from Indiana University and his Ph.D. in Mathematics from the University of Iowa. His research specializes in quantum topology with a focus on knot invariants.
Abstract: A common theme in many areas of mathematics is to find a simpler representation of an object indirectly by expressing it as the projection of an object in some higher-dimensional space. In 1991 Yannakakis proved a remarkable connection between a lifted representation of a polytope and the nonnegative rank of a matrix associated to the polytope. In recent years, this idea has been generalized to cone lifts of convex sets, with applications in, and tools coming from, many areas of mathematics and theoretical computer science. This talk will survey the central ideas, results, and questions in this field.
About the Hayden-Howard lecture: The Hayden-Howard lecture was inaugurated in the spring of 2001 by a generous contribution from a friend of the Department of Mathematics. The lecture series was established in honor of mathematics professors Thomas Hayden and Henry Howard. Each year, the lecture series brings a research mathematician of international stature to the University of Kentucky.
