Higher order Levi forms on homogeneous CR manifolds
Stefano Marini, Costantino Medori, Mauro Nacinovich
We investigate the nondegeneracy of higher order Levi forms on weakly nondegenerate homogeneous manifolds. Improving previous results, we prove that general orbits of real for…
On some classes of Z-graded Lie algebras
Stefano Marini, Costantino Medori, Mauro Nacinovich
We study finite dimensional almost and quasi-effective prolongations of nilpotent Z-graded Lie algebras, especially focusing on those having a decomposable reductive structural sub…
On transitive contact and algebras
Stefano Marini, Costantino Medori, Mauro Nacinovich +1
We consider locally homogeneous manifolds and show that, under a condition only depending on their underlying contact structure, their automorphisms form a finite dimensi…
Stochastic homogenization of maximal monotone relations and applications
Luca Lussardi, Stefano Marini, Marco Veneroni
We study the homogenization of a stationary random maximal monotone operator on a probability space equipped with an ergodic dynamical system. The proof relies on Fitzpatrick's var…
