SUMMARY:Algebraic geometry seminar
CLASS:PUBLIC
DESCRIPTION:CATHERINE ST-PIERRE\, UNIVERSITY OF WATERLOO\n\n_Group Actions 
 in Non-Commutative Algebraic Geometry: a survey of\nhomological property a
 nd invariants_\n\nWe survey non-commutative analogues of classical regular
 ity\,\nGorenstein\, and Cohen-Macaulay properties in the framework of\nArt
 in-Schelter. After reviewing the foundational homological\nproperties that
  govern this theory\, we will focus on the structure of\ninvariant rings u
 nder group and Hopf algebra actions and review some\nnoncommutative analog
 ues of classical results in invariant theory to\ncharacterize the invarian
 t rings of noncommutative rings. The talk\nconcludes with new results exte
 nding this invariant-theoretic\nframework.\n\nMC 5403
