Linear stabilization for a degenerate wave equation in non divergence form with drift
Genni Fragnelli, Dimitri Mugnai
We consider a degenerate wave equation in one dimension, with drift and in presence of a leading operator which is not in divergence form. We impose a homogeneous Dirichlet boundar…

Fourth order differential operators with interior degeneracy and generalized Wentzell boundary conditions
Alessandro Camasta, Genni Fragnelli
In this paper we consider the fourth order operators A1u := (au")" and A2u := au"" in divergence form and non divergence form, respectively, where a, defined in [0, 1] with values…

Degenerate fourth order parabolic equations with Neumann boundary conditions
Alessandro Camasta, Genni Fragnelli
We study the generation property for a fourth order operator in divergence or in non divergence form with suitable Neumann boundary conditions. As a consequence we obtain the well…
