Stability for some classes of degenerate nonlinear hyperbolic equations with time delay
Alessandro Camasta, Genni Fragnelli, Cristina Pignotti
We consider several classes of degenerate hyperbolic equations involving delay terms and suitable nonlinearities. The idea is to rewrite the problems in an abstract way and, using…
New results on controllability and stability for degenerate Euler-Bernoulli type equations
Alessandro Camasta, Genni Fragnelli
In this paper we study the controllability and the stability for a degenerate beam equation in divergence form via the energy method. The equation is clamped at the left end and co…
A stability result for a degenerate beam equation
Alessandro Camasta, Genni Fragnelli
We consider a beam equation in presence of a leading degenerate operator which is not in divergence form. We impose clamped conditions where the degeneracy occurs and dissipative c…
Boundary controllability for a degenerate beam equation
Alessandro Camasta, Genni Fragnelli
The paper deals with the controllability of a degenerate beam equation. In particular, we assume that the left end of the beam is fixed, while a suitable control acts on the ri…
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…
A degenerate operator in non divergence form
Alessandro Camasta, Genni Fragnelli
In this paper we consider a fourth order operator in nondivergence form , where is a function that degenerates somewhere in the int…
