"On the quadratic dual of the Fomin-Kirillov algebras"

This talk will be based on recent joint work with James Zhang on the quadratic dual (aka Koszul dual) of the Fomin-Kirillov algebras. It will include a brief review of nice ring-theoretic and homological properties of noncommutative graded algebras. No prior knowledge is assumed and open questions will be provided at the end.

"Hilbert space operators with compatible off-diagonal corners"

Given a complex, separable Hilbert space $\mathcal{H}$, we characterize those operators for which $\| P T (I − P ) \| = \| (I − P )T P \|$  for all orthogonal projections $P$ on $\mathcal{H}$.
