Partial differential equations with piecewise constant delay

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 14, Issue 3, Page 485-496, 1991., 1990
The influence of certain discontinuous delays on the behavior of solutions to partial differential equations is studied. In Section 2, the initial value problems (IVP) are discussed for differential equations with piecewise constant argument (EPCA) in partial derivatives.

A survey on some vanishing viscosity limit results

open access: yesAdvances in Nonlinear Analysis, 2023
We present a survey concerning the convergence, as the viscosity goes to zero, of the solutions to the three-dimensional evolutionary Navier-Stokes equations to solutions of the Euler equations.

A Ginzburg-Landau type energy with weight and with convex potential near zero

open access: yes, 2020
In this paper, we study the asymptotic behaviour of minimizing solutions of a Ginzburg-Landau type functional with a positive weight and with convex potential near $0$ and we estimate the energy in this case.

Time-dependent attractor of wave equations with nonlinear damping and linear memory

open access: yesOpen Mathematics, 2019
In this article, we consider the long-time behavior of solutions for the wave equation with nonlinear damping and linear memory. Within the theory of process on time-dependent spaces, we verify the process is asymptotically compact by using the ...

The NLS equation in dimension one with spatially concentrated nonlinearities: the pointlike limit

open access: yes, 2014
In the present paper we study the following scaled nonlinear Schr\"odinger equation (NLS) in one space dimension: \[ i\frac{d}{dt} \psi^{\varepsilon}(t) =-\Delta\psi^{\varepsilon}(t) + \frac{1}{\epsilon}V\left(\frac{x}{\epsilon}\right)|\psi^{\varepsilon}(

Competition and boundary formation in heterogeneous media: Application to neuronal differentiation [PDF]

open access: yes, 2014
We analyze an inhomogeneous system of coupled reaction-diffusion equations representing the dynamics of gene expression during differentiation of nerve cells. The outcome of this developmental phase is the formation of distinct functional areas separated

Characterizing the strange term in critical size homogenization: Quasilinear equations with a general microscopic boundary condition

open access: yesAdvances in Nonlinear Analysis, 2017
The aim of this paper is to consider the asymptotic behavior of boundary value problems in n-dimensional domains with periodically placed particles, with a general microscopic boundary condition on the particles and a p-Laplace diffusion operator on the ...
