»On the generalised Dubrovin's conjecture for Grassmannians«

The classical Dobrovin’s conjecture states that for a smooth projective variety existence of a full exceptional collection in its bounded derived category of coherent sheaves is equivalent to generic semi-simplicity of its (big) quantum cohomology. Galkin, Mellit, and Smirnov observed a couple of years ago that Dubrovin’s conjecture does not hold if one considers small quantum cohomology instead. Motivated by the latter result, Kuznetsov and Smirnov have recently proposed an extension to Dubrovin’s conjecture which deals with the latter phenomenon. We will give an overview of the problem and sketch a proof of this generalised Dubrovin’s conjecture for Grassmannians.
