Roman Krutowski:Maslov Index Formula in Heegaard Floer Homology
发布人
https://www.youtube.com/watch?v=weIAnv2kICU Institute for Advanced Study Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar Three 20-min Research Talks Seminar site:http://www.math.tau.ac.il/~sarabt/zoominar/ Topic: Maslov Index Formula in Heegaard Floer Homology Speaker: Roman Krutowski Affiliation: University of California, Los Angeles Date: April 21, 2023 The formula introduced by Robert Lipshitz for Heegaard Floer homology is now one of the basic tools for those working with HF homology. The convenience of the formula is due to its combinatorial nature. In the talk, we will discuss the recent combinatorial proof of this formula. Roman Krutowski——《Combinatorial proof of Maslov index formula in Heegaard Floer Theory》:https://doi.org/10.48550/arXiv.2206.05221 We prove Lipshitz's Maslov index formula in Heegaard Floer homology via the combinatorics of Heegaard diagrams.
