Panorama of Geometry and Topology

Talk 1: Vincent Rodgers (UI Physics Dept)

Topic: Projective Gauged Gravity
Abstract:

In 2 dimensions (2D), Einstein’s theory of general relativity becomes classically trivial. Yet when one studies the symmetries of 2D gravitation through string theory, new fields arise from string symmetries. As it turns out, these fields have meaning in higher dimensions through symmetries found in geodesics.  In this talk we will discuss how these fields merge with general relativity, interact with matter, and how they might be candidates for dark energy and dark matter. Throughout we also discuss how theoretical physicists develop new mathematical ideas from symmetry.

Talk 2: Colin Adams (Williams College)

Topic: "Blown Away: What Knot to Do When Sailing” by Sir Randolph Bacon III, cousin-in-law to Colin Adams
Abstract:

Being a tale of adventure on the high seas involving great risk to the tale teller, and how an understanding of the mathematical theory of knots saved his bacon. No nautical or mathematical background assumed.
