Title: On the Morin problem
​
Abstract:
We will study the Morin problem about the classification of
finite complete configurations of incident planes in P^5.
We show that each such configuration occurs as a subset of the singular
locus of a projective model of a moduli space of twisted sheaves on a K3
surface.  As a result we show that there is a unique maximal configuration
of 20 incident planes in P^5. Moreover, we classify complete
configurations of 19 planes.
This is a joint work in progress with A. Verra.
