Nicholas Wilkins, University of Oxford will give a lecture "The quantum Steenrod square and related operations" in the frame of Symplectic topology Seminar on Tuesday, Dec 18, 2018 from 16:00 to 18:00 in room 821.

Abstract: The Steenrod square is a ring homomorphism from the cohomology of a topological space to the Z/2-equivariant cohomology of this space (with the trivial Z/2-action). Given a closed monotone symplectic manifold, we will define a deformed notion of the Steenrod square for quantum cohomology, which will not in general be a ring homomorphism, and talk about some properties and calculations. We will then frame these in the broader setting of Seidel’s equivariant pair-of-pants product.
