Nilpotent matrices having a given Jordan type as maximum commuting nilpotent orbit

Anthony Iarrobino, Leila Khatami, Bart Van Steirteghem +1

The Jordan type of a nilpotent matrix is the partition giving the sizes of its Jordan blocks. We study pairs of partitions $(P, Q)$ , where $Q = Q (P)$ is the Jordan type of…

The moduli scheme of affine spherical varieties with a free weight monoid

Paolo Bravi, Bart Van Steirteghem

We study Alexeev and Brion's moduli scheme $M_{Γ}$ of affine spherical varieties with weight monoid $Γ$ under the assumption that $Γ$ is free. We describe the tangent space to $M_{Γ}$ …
