On asymptotic effects of boundary perturbations in exponentially shaped Josephson junctions
Monica De Angelis, Pasquale Renno
A parabolic integro differential operator L, suitable to describe many phenomena in various physical fields, is considered. By means of equivalence between L and the third order eq…
Asymptotic effects of boundary perturbations in excitable systems
M. De Angelis, P. Renno
A Neumann problem in the strip for the Fitzhugh Nagumo system is consid- ered. The transformation in a non linear integral equation permits to deduce a priori estimates for the sol…
Diffusion and wave behaviour in linear Voigt model
Monica De Angelis, Pasquale Renno
A boundary value problem related to a third- order parabolic equation with a small parameter is analized. This equation models the one-dimensional evolution of many dissipative med…
On fast and slow times in models with diffusion
M. De Angelis, A. M. Monte, P. Renno
The linear Kelvin{Voigt operator L_εis a typical example of wave operator L_0 perturbed by higher-order viscous terms as \epsilonu_xxt. If Pεis a prefixed boundary value problem fo…
Wave hierarchies in viscoelasticity
M. De Angelis, P. Massarotti, P. Renno
An evolution operator L_n with n arbitrary, typical of several models, is analyzed. When n= 1, the operator characterizes the standard linear solid of viscoelasticity, whose proper…
Existence, uniqueness and a priori estimates for a non linear integro-differential equation
M. De Angelis, P. Renno
The paper deals with the explicit calculus and the properties of the fundamental solution K of a parabolic operator related to a semilinear equation that models reaction diffusion…
On the Fitzhugh-Nagumo model
M. De Angelis, P. Renno
The initial value problem P0, in all of the space, for the spatio - temporal FitzHugh - Nagumo equations is analyzed. When the reaction kinetics of the model can be outlined by mea…
