Free divisors in prehomogeneous vector spaces
Michel Granger, David Mond, Mathias Schulze
We study linear free divisors, that is, free divisors arising as discriminants in prehomogeneous vector spaces, and in particular in quiver representation spaces. We give a charact…

A solvability criterion for the Lie algebra of derivations of a fat point
Mathias Schulze
We consider the Lie algebra of derivations of a zero dimensional local complex algebra. We describe an inequality involving the embedding dimension, the order, and the first deviat…
