Multiplicative formulas in Cohomology of and in quiver representations

Nicolas Ressayre

Consider a partial flag variety which is not a grassmaninan. Consider also its cohomology ring ${\rm H}^*(X,\ZZ)$ endowed with the base formed by the Poincaré dual classes of t…

A smooth counterexample to Nori's conjecture on the fundamental group scheme

Christian Pauly

We show that Nori's fundamental group scheme π(X,x) does not base change correctly under extension of the base field for certain smooth projective ordinary curves X of genus 2 defi…
