摘 要：in this talk, we study the cohomological annihilators introduced by iyengar and takahashi. let r be anequicharacteristiccompletegorensteinlocal ring over an algebraically closed field of characteristic zero. if the cohomological annihilator of r is the maximal ideal, we prove that r has finite cohen-macaulay type if the krull dimension of r is less or equal to one. this is a joint work withsouvikdey.
