Normalized Solutions with Positive Energies for a Coercive Problem and Application to the Cubic-Quintic Nonlinear Schrodinger Equation [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2021
. In any dimension N ≥ 1, for given mass m > 0 and when the C 1 energy functional is coercive on the mass constraint we are interested in searching for constrained critical points at positive energy levels.

Higher integrability of the gradient for the thermal insulation problem [PDF]

open access: yesInterfaces and free boundaries (Print), 2021
We prove the higher integrability of the gradient for local minimizers of the thermal insulation problem, an analogue of De Giorgi’s conjecture for the Mumford-Shah functional. We deduce that the singular part of the free boundary has Hausdorff dimension

Qualitative analysis for the nonlinear fractional Hartree type system with nonlocal interaction

open access: yesAdvances in Nonlinear Analysis, 2021
In the present paperwe study the existence of nontrivial solutions of a class of static coupled nonlinear fractional Hartree type system. First, we use the direct moving plane methods to establish the maximum principle(Decay at infinity and Narrow region

Infinitely many radial and non-radial sign-changing solutions for Schrödinger equations

open access: yesAdvances in Nonlinear Analysis, 2022
In the present paper, a class of Schrödinger equations is investigated, which can be stated as −Δu+V(x)u=f(u),    x∈ℝN.- \Delta u + V(x)u = f(u),\;\;\;\;x \in {{\rm{\mathbb R}}^N}.

Intertwining semiclassical solutions to a Schrödinger-Newton system [PDF]

open access: yes, 2011
We study the problem ( (−"i∇ + A(x)) 2 u + V (x)u = " 2 1 |x| ∗ |u| 2 u, u ∈ L 2 (R 3 ,C), "∇u + iAu ∈ L 2 (R 3 ,C 3 ), where A: R3 → R3 is an exterior magnetic potential, V : R3 → R is an exte- rior electric potential, and " is a small positive ...

A Generalized Version of the Lions-Type Lemma

open access: yesAnnales Mathematicae Silesianae, 2023
In this short paper, I recall the history of dealing with the lack of compactness of a sequence in the case of an unbounded domain and prove the vanishing Lions-type result for a sequence of Lebesgue-measurable functions.

Existence and Regularity of a Weak Solution to a Class of Systems in a Multi-Connected Domain

open access: yesJournal of Partial Differential Equations, 2019
We consider the existence and regularity of a weak solution to a class of systems containing a p-curl system in a multi-connected domain. This paper extends the result of the regularity theory for a class containing a p-curl system that is given in the ...

Landesman-Lazer condition revisited: the influence of vanishing and oscillating nonlinearities [PDF]

open access: yes, 2015
In this paper we deal with semilinear problems at resonance. We present a sufficient condition for the existence of a weak solution in terms of the asymptotic properties of nonlinearity.
