# MIT COMBINATORICS SEMINAR

# Hidden Symmetries of Gromov-Witten Invariants

## Room 2-338

Gromov-Witten invariants of flag manifolds generalize the intersection numbers
of Schubert varieties (aka Littlewood-Richardson coefficients). Their study
and explicit calculation is an important problem in quantum Schubert calculus.
The aim of the talk is to present certain symmetries of these invariants under
the action of cyclic groups.
This allows one to calculate 1/n of all these invariants.
