On fractional semilinear wave equations in non-cylindrical domains

Mauro Bonafini, Van Phu Cuong Le, Riccardo Molinarolo

In this paper, we investigate a class of semilinear wave equations in non-cylindrical time-dependent domains, subject to exterior homogeneous Dirichlet conditions. Under mild regul…

On the eigenvalues of the biharmonic operator on annuli

Davide Buoso, Riccardo Molinarolo

We show that the fundamental tone of the bilaplacian with Dirichlet or Navier boundary conditions on radially symmetric domains is always simple in dimension . In dimension…

Shape perturbation of a nonlinear mixed problem for the heat equation

Matteo Dalla Riva, Paolo Luzzini, Riccardo Molinarolo +1

We consider the heat equation in a domain that has a hole in its interior. We impose a Neumann condition on the exterior boundary and a nonlinear Robin condition on the boundary of…

Existence result for a nonlinear mixed boundary value problem for the heat equation

Riccardo Molinarolo

In this paper we study the existence of solutions in parabolic Schauder space of a nonlinear mixed boundary value problem for the heat equation in a perforated domain. From a given…
