U okviru Seminara za simplektičku topologiju u utorak, 18. decembra 2018 u terminu od 16 do 18 časova, Nikolas Vilkins sa Univerziteta u Oksfordu (Nicholas Wilkins, University of Oxford) održaće predavanje u sali 821.


Naslov predavanja: THE QUANTUM STEENROD SQUARE AND RELATED OPERATIONS

Apstrakt:
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.
