SUMMARY:The Second Vanishing Theorem in Ramified Mixed Characteristic
DESCRIPTION:Speaker: Alex Scheffelin\, Columbia University\n\nTo a triple of a ring $R$, an $R$-module $M$, and an ideal $I$ we can associate the local cohomology modules $H^n_I(M)$. One classical problem dating back to a question of Grothendieck is to identify when these vanish for all $n i$ and all modules $M$, the smallest such $i$ we denote the …
