Title: On Kashaev's simple model of 4d TQFT and realizations of Pancher moves

Date: May 18, 2017, 16:00 - 17:30

Place: SR 7, 2. OG, Oskar Morgenstern Platz 1, University of Vienna

First I will review an elementary approach of Rinat Kashaev to construct invariants of 4-dimensional manifolds, and then elaborate on his proposal to "linearize" spaces of stable rational curves with marked points.
Main reference is two Kashaev's papers: "A simple model of 4d TQFT" (arXiv:1405.5763) and "On realizations of Pachner moves in 4D" (arXiv:1504.01979, especially formula (32)).
