Title: Indiana Pols Forced to Eat Humble Pi, The Curious History of an Irrational Number Speaker: Prof. Edray Goins, Pomona College In 1897, Indiana physician Edwin J. Goodwin believed he had discovered a way to square the circle, and proposed a bill to Indiana Representative Taylor I. Record which would secure Indiana’s the claim to […]
Title: Experimental Knot Music Abstract: In knot theory, there are algebraic structures we can use to distinguish different types of knots and links. In this talk we will ask an unexpected question: what do they sound like? We will see a number of techniques I have been developing for interpreting knot-theoretic structures as elements of […]

Title: Space vectors forming rational angles Abstract: We classify all possible configurations of vectors in three-dimensional space with the property that any two of the vectors form an angle whose measure is a rational multiple of π. As a corollary, we find all tetrahedra whose six dihedral angles are all rational multiples of π.While these […]
We propose a regularization and variable selection method, named arbitrary rectangle-range generalized elastic net (ARGEN). It can be applied in high dimensional sparse linear regression models. We propose an algorithm […]

Nonlocal theories have emerged with powerful models and methods to analyze and predict complex phenomena. Different versions of nonlocal operators have been proposed, each with its advantages and challenges. In […]
Title: A competent translation/a pitiful bungle: The Foundations of Geometry Abstract: David Hilbert’s Grundlagen der Geometrie is a rare example of a historical mathematics text that is still profitably read […]
This talk focuses on using a multiwavelet representation of the discontinuous Galerkin (DG) approximation for trouble cell indication. The multiwavelet representation is related to the jumps in the (derivatives of) […]
Title: Unsolved Mathematics at Burning Man Abstract: Rising 12 feet tall with an 18-foot wingspan, a 2-ton unfolding dodecahedron comes to life at Burning Man, the world’s most influential large-scale […]
