Infinitely many free or prescribed mass solutions for fractional Hartree equations and Pohozaev identities

open access: yesAdvanced Nonlinear Studies
In this paper we study the following nonlinear fractional Hartree (or Choquard-Pekar) equation (−Δ)su+μu=(Iα*F(u))F′(u) inRN, ${\left(-{\Delta}\right)}^{s}u+\mu u=\left({I}_{\alpha }{\ast}F\left(u\right)\right){F}^{\prime }\left(u\right)\quad \text{in} {\

On quasilinear elliptic equations in ℝN

open access: yesAbstract and Applied Analysis, Volume 1, Issue 4, Page 407-415, 1996., 1996
In this note we give a result for the operator p‐Laplacian complementing a theorem by Brézis and Kamin concerning a necessary and sufficient condition for the equation −Δu = h(x)uq in ℝN, where 0 < q < 1, to have a bounded positive solution. While Brézis and Kamin use the method of sub and super solutions, we employ variational arguments for the ...

Bifurcation and multiplicity results for critical problems involving the p-Grushin operator

open access: yesAdvances in Nonlinear Analysis
In this article, we prove a bifurcation and multiplicity result for a critical problem involving a degenerate nonlinear operator Δγp{\Delta }_{\gamma }^{p}. We extend to a generic p>1p\gt 1 a result, which was proved only when p=2p=2. When p≠2p\ne 2, the

A multiplicity result for the scalar field equation

open access: yes, 2013
We prove the existence of $N - 1$ distinct pairs of nontrivial solutions of the scalar field equation in ${\mathbb R}^N$ under a slow decay condition on the potential near infinity, without any symmetry assumptions.

A weighted Hardy-type inequality for 0

open access: yes, 2015
Hardy-type inequalities with sharp costants for 0 < p < 1 for power weight functions were established in [10], [5]. In this work, we give an extension of these inequalities for general weight functions, prove the existence of extremal functions and write
