Comparing the commutative and non-commutative resolutions for determinantal varieties of skew symmetric and symmetric matrices
Špela Špenko, Michel Van den Bergh
Let Y be the variety of (skew) symmetric nxn-matrices of rank less than or equal to r. In paper we construct a full faithful embedding between the derived category of a non-commuta…

Sweeping words and the length of a generic vector subspace of M_n(F)
Igor Klep, Špela Špenko
The main result of this short note is a generic version of Paz's conjecture on the lengths of generating sets in matrix algebras. Consider a generic g-tuple A=(A_1,..., A_g) of nxn…

Non-commutative resolutions of quotient singularities
Špela Špenko, Michel Van den Bergh
In this paper we generalize standard results about non-commutative resolutions of quotient singularities for finite groups to arbitrary reductive groups. We show in particular that…
