Seminario / M. Kapustka & G. Kapustka


Nell'ambito del seminario congiunto di geometria algebrica organizzato dai Dipartimenti di Matematica dell'Università e del Politecnico di Milano,

lunedì 26 marzo a partire dalle 14:30

presso l'Aula C del Dipartimento di Matematica dell'Università di Milano si terranno i seguenti seminari:

ore 14:30


 Michal Kapustka
(University of Stavanger and Jagiellonian University Krakow)
Hodge equivalent Calabi-Yau threefolds withGLSM interpretation

Abstract: I will speak about joint work with Marco Rampazzo. I will present a construction of pairs of derived equivalent L-equivalent and Hodge equivalent Calabi-Yau threefolds which are not birational. The equivalence will then be interpreted in terms of wall crossing in a suitable gauged linear sigma model.

ore 15:30


Grzegorz Kapustka
(Jagiellonian University Krakow)
On the Morin problem

Abstract: We will study the Morin problem and present a method of classification of finite complete families of incident planes in ℙ^5 as a result we prove that there is exactly one, up to Aut(P^5), configuration of maximal cardinality 20 and a unique one parameter family containing all the configurations of 19 planes. The method is to study projective models of appropriated moduli spaces of twisted sheaves on K3 surfaces. This is a joint work with A. Verra.
