Richardson Varieties Have Kawamata Log Terminal Singularities

Shrawan Kumar, Karl Schwede

Let $X_{w}^{v}$ be a Richardson variety in the full flag variety $X$ associated to a symmetrizable Kac-Moody group $G$ . Recall that $X_{w}^{v}$ is the intersection of the finite dimensiona…

An approach towards the Kollár-Peskine problem via the Instanton Moduli Space

Shrawan Kumar

We look at the following question raised by Kollár and Peskine. (Actually, it is a slightly weaker version of their question.) Let $V_{t}$ be a family of rank two vector bundles on $…
