Николас Вилкинс са Универзитета у Оксфорду (Nicholas Wilkins, University of Oxford) одржаће предавање The quantum Steenrod square and related operations у оквиру семинара за Симплектичку топологију у уторак 18. децембра 2018. у термину од 16 до 18 сати у сали 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.
