Наслов предавања: MINIMAL FILLING DIAGRAM LEMMA FOR 7-LOCATED SIMPLICIAL COMPLEXES
Апстракт: This is joint work with Nima Hoda (Cornell University). 7-location is a generalized combinatorial nonpositive curvature condition for flag simplicial complexes introduced by Osajda. We show that weakly systolic complexes are 7-located. We compare 7-location to systolicity. We investigate the existence of a CAT(0) metric on a 7-located disc endowed with a certain metric. We prove the Minimal Filling Diagram Lemma for 7-located, locally 5-large complexes. We conclude that such complexes have quadratic isoperimetric function.
