Westminster College’s Department of Mathematics and Computer Science hosted a colloquium featuring alumnus Richard Ligo ’12 as the guest speaker.

Ligo, a doctoral candidate in mathematics at the University of Iowa, presented an introduction to his research, “A Taste of Differential Geometry: Ribbons and White’s Formula.”

From Ligo’s abstract: “A traditional course in multivariable calculus introduces vectors and curves in three space. The combination of these two ideas leads to the definition of a ribbon. From this construction the link, writhe and twist of a ribbon can be defined, a relationship that is governed by White’s formula. These ideas can be applied to the problem of determining the minimum energy configurations of elastic rods.”
