Identification of a diffusion coefficient in strongly degenerate parabolic equations with interior degeneracy
Genni Fragnelli, Gabriela Marinoschi, Rosa Maria Mininni +1
We study two identification problems in relation with a strongly degenerate parabolic diffusion equation characterized by a vanishing diffusion coefficient wit…
Non-trivial, non-negative periodic solutions of a system of singular-degenerate parabolic equations with nonlocal terms
Genni Fragnelli, Dimitri Mugnai, Paolo Nistri +1
We study the existence of non-trivial, non-negative periodic solutions for systems of singular-degenerate parabolic equations with nonlocal terms and satisfying Dirichlet boundary…
Asymptotic parabolicity for strongly damped wave equations
Genni Fragnelli, Gisèle Ruiz Goldstein, Jerome A. Goldstein +1
For a positive selfadjoint operator on a Hilbert space, \[ \frac{d^2u}{dt}(t) + 2 F(S)\frac{du}{dt}(t) + S^2u(t)=0 \] describes a class of wave equations with strong friction o…
