Symmetry and enumerative geometry

馃搫 ABSTRACT /听R脡SUM脡听

Enumerative geometry is the art and science of counting geometric things, for instance there are 27 lines on a cubic surface, 28 bitangents to a planar quartic, etc. Enumerative questions first appeared in ancient Greek geometry, and flourished during the French school of projective geometry in the 19th century. Today this discipline enjoys wide-reaching connections throughout mathematics and physics.

In this talk we鈥檒l explore classical enumerative questions in the presence of some ambient symmetry. We鈥檒l discuss how finite symmetries of an enumerative problem manifest both in the geometric solutions of the problem and in the process of algebraically solving for these solutions.
