Title:  Galois groups in Enumerative Geometry and Applications

ABSTRACT:  In 1870 Jordan explained how Galois theory can be applied to problems from enumerative geometry, with the group encoding

intrinsic structure of the problem. Earlier Hermite showed the equivalence of Galois groups with geometric monodromy groups, and in 1979 Harris initiated the modern study of

Galois groups of enumerative problems. He posited that a Galois group should be `as large as possible' in that it will be the largest group preserving internal symmetry in the geometric problem.

 

I will describe this background and discuss some work in a long-term project to compute, study, and use Galois groups of geometric problems, including those that arise    

in applications of algebraic geometry. A main focus is to understand Galois groups in the Schubert calculus, a well-understood class of geometric problems that has long

served as a laboratory for testing new ideas in enumerative geometry.
