Monotonicity and nonexistence results for some fractional elliptic problems in the half space

Mouhamed Moustapha Fall, Tobias Weth

We study a class of fractional elliptic problems of the form $\Ds u= f(u)$ in the half space $R_{+}^{N} := {x \in R^{N} : x_{1} > 0}$ with the complementary Dirichlet condition $u \equi…

Real solutions to the nonlinear Helmholtz equation with local nonlinearity

Gilles Evequoz, Tobias Weth

In this paper, we study real solutions of the nonlinear Helmholtz equation $- Δ u - k^{2} u = f (x, u), x \in R^{N}$ satisfying the asymptotic conditions $$ u(x)=O(|x|^{\frac{1-…

Asymptotic symmetry for a class of nonlinear fractional reaction-diffusion equations

Sven Jarohs, Tobias Weth

We study the nonlinear fractional reaction diffusion equation $\partial_{t} u + (- Δ)^{s} u = f (t, x, u)$ , $s \in (0, 1)$ in a bounded domain $Ω$ together with Dirichlet boundary condition…
