Participating: Ilya Smirnov (BCAM)
Lech’s inequality connects multiplicity and colength, two fundamental invariants of an ideal. Lech showed that the inequality is never sharp in dimension at least 2. I will explain why a sharper inequality might be useful, discuss potential ways to do so, present partial results, and pose open problems.
