Trace and Hardy-Sobolev type inequalities and applications to a quasilinear elliptic problem in half-space

Loïc Constantin, Ranieri França Freire, Jacques Giacomoni

In the present paper we are dealing with the following quasilinear elliptic problem: \begin{equation*} \begin{cases} -\mathrm{div}(ρ(x_N) |\nabla u|^{p-2}\nabla u) =a|u|^{s-2}u &\…

A matrix-based spectral method for the numerical approximation of the fractional Laplacian and the fractional -Laplacian of functions defined on

Loïc Constantin, Carlota M. Cuesta, Francisco de la Hoz

Given a function defined on , its fractional -Laplacian is given by $$(-Δ)_p^su(\vec x)=C_1(n,s,p)\int_{\mathbb R^n}\frac{|u(\vec x)-u(\vec y)|^{p-2}(u(\vec x)…
