SUMMARY:Colloquium
CLASS:PUBLIC
DESCRIPTION:GUOLIANG YU\, TEXAS A&M UNIVERSITY\n\n\"INDEX THEORY OF THE DIR
 AC OPERATOR ON MANIFOLDS WITH POLYHEDRAL\nBOUNDARY AND ITS APPLICATIONS\"\
 n\nI will introduce a new index theory for Dirac operators on manifolds\nw
 ith polyhedral boundary and discuss how this theory can be applied\nto so
 lve Gromov's dihedral extremality conjecture on scalar\ncurvature. This i
 s joint work with Jinmin Wang and Zhizhang Xie. This\ntalk will be accessi
 ble to non-experts including graduate students.\n\nMC 5501
