The Lazer-McKenna conjecture for an elliptic problem with critical growth, part II
We consider an elliptic problem of Ambrosetti–Prodi type involving critical Sobolev exponent. We prove that this problem has solutions blowing up near the boundary of the domain.
An Elliptic Problem Related to Planar Vortex Pairs
In this paper, we study the existence and limiting behavior of the mountain pass solutions of the elliptic problem —Δu = λf(u — q(x)) in Ω C ℝ²; u 0 on ∂Ω, where q is a positive harmonic function. We show that the 'vortex core' Aλ = {x ∈ Ω: uλ (x) > q(x)} of the solution uλ, shrinks to a global minimum point of q on the boundary ∂Ω as λ → + ∞. Furthermore, we show that for each strict local minimum x₀ point of q(x) on the boundary ∂Ω, there exists a solution uλ whose vortex core shrinks to this strict local minimum point x₀ as λ → +∞.
Solutions with boundary layer and positive peak for an elliptic Dirichlet problem
In this paper, we study existence of solutions with boundary layer and peaks for an elliptic problem. We prove that the problem has a mountain-pass-type solution, which has a boundary layer and a single peak near the boundary. Moreover, we also study the existence of solutions with interior peak.
An elliptic problem with critical growth in domains with shrinking holes
We study an elliptic problem involving critical Sobolev exponent in domains with small holes. We prove the existence of solutions which blow up like a volcano near the centre of each hole.
Infinitely Many Positive Solutions for Nonlinear Schrödinger-Poisson System
In this paper, simulated by the paper of Wei and Yan [33] (see also [30–32]), we intend to find infinitely many positive solutions to (1.2) for all p ∈ (1, 5) under weaker integrability conditions on K(y) and Q(y). In [33], a single equation, this is, K(y) ≡ 0 in (1.2), was studied and infinitely many non-radial solutions were found in the case that Q(y) is radial. For this, they employed a very novel idea, that is, they use k, the number of the bumps of the solutions, as the parameter to construct Infinitely Many Solutions for Schrödinger-Poisson System 1071 spike solutions for the Schrödinger equation considered.
