Title: Associated primes of local cohomology of flat extensions with regular fibers
Abstract: In this talk, we will discuss the following question raised by Mel Hochster: let $(R,m,K)$ be a local ring and $S$ be a flat extension with regular closed fiber. Is the set of associated primes of $H^i_I(S)$ that contain $mS$ finite for every ideal $I\subset S$ and every $i\in \mathbb{N}$? We will explore, using several tools from homological algebra, cases in which the answer is positive.
