Double phase inequalities with convolution nonlinearity in exterior domains
Marius Ghergu
We discuss the existence of -solutions for two related double phase inequalities: \begin{equation*} {\mathcal L}_g u\pm Δ_s u\geq (|x|^{-α}*u^p)u^q \quad\mbox{ in }\mathbb R^N…
Isolated singularities for elliptic equations with convolution terms in a punctured ball
Marius Ghergu, Zhe Yu
The purpose of this article is two-fold. First, we investigate the inequality $$ -Δu+V(x) u\geq f\quad\mbox{ in } B_1\setminus\{0\}\subset \mathbb{R}^N , N \geq 2, $$ where $f\in L…
The Gierer-Meinhardt system in the entire space with non-local proliferation rates
Marius Ghergu, Nikos I. Kavallaris, Yasuhito Miyamoto
In this work, we present a novel stationary Gierer-Meinhardt system incorporating non-local proliferation rates, defined as follows: $$ \begin{cases} \displaystyle -Δu+λu=\frac{J*u…
Superharmonic functions in the upper half space with a nonlocal boundary condition
Marius Ghergu
We discuss the existence of positive superharmonic functions in , , in the sense for some Radon measure ,…
Steady-states of the Gierer-Meinhardt system in exterior domains
Marius Ghergu, Jack McNicholl
We discuss the existence and nonexistence of solutions to the steady-state Gierer-Meinhardt system $$ \begin{cases} \displaystyle -Δu=\frac{u^p}{v^q}+λρ(x) \,, u>0 &\quad\mbox{ in…
Asymptotically homogeneous solutions of the supercritical Lane-Emden system
Louis Dupaigne, Hatem Hajlaoui, Marius Ghergu
We consider the Lane-Emden system-u = |v| p-1 v,-v = |u| q-1 u in R d. When p q 1, it is known that there exists a positive radial stable solution (u, v) C…
