Existence of solution to a Cahn–Hilliard equation

Asymptotic Analysis, 2022
Our aim in this paper is to prove the existence to a Cahn–Hilliard equation with a proliferation term and endowed with Neumann boundary conditions. Such a model has, in particular, applications in biology. We first consider regular nonlinear term then logarithmic one. We finally give some numerical simulations which confirm the theoretical results.

Existence of a Nonstationary Poiseuille Solution

Siberian Mathematical Journal, 2005
Let \(\omega\) be a bounded domain in \(\mathbb R^n\), \(Q_T = \omega\times(0,T)\). The following inverse problem is studied in \(Q_T\): \[ \begin{gathered} v_t(x,t) - \nu\Delta\,v(x,t) = q(t),\quad (x,t)\in Q_T, \\ v(x,t) = 0, \quad (x,t) \in \partial\omega\times(0,T),\quad v(x,0) = a(x),\quad x\in\omega, \\ \int_{\omega}v(x,t)\,dx = F(t)\;\;\text ...

Existence of solutions for a class of integral equations

Differential and Integral Equations, 2022
Let \(\rho:\mathbb{R}^N\to\mathbb{R}\) be a suitable positive, bounded, continuous function and let \(K:\mathbb{R}^N\times\mathbb{R}^N\to\mathbb{R}\) be an appropriate non-negative, continuous function. The aim of this paper is devoted to study, by variational methods, the following two nonlocal problems:\[L_Ku=\rho(x)|u|^{p-1}u,\quad\text{in }\mathbb ...
