Uniqueness of Single Peak Solutions for a Kirchhoff Equation
MathematicsWe deal with the following singular perturbation Kirchhoff equation: −ϵ2a+ϵb∫R3|∇u|2dyΔu+Q(y)u=|u|p−1u,u∈H1(R3), where constants a,b,ϵ>0 and ...

Peak solutions for the fractional Nirenberg problem [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 2015 In this paper, the fractional order curvature equation $(-Δ)^γu = (1 + \varepsilon K(x))u^{\frac{N + 2γ}{N - 2γ}}$ in $\mathbb{R}^N$ is considered. Assuming $K(x)$ has two critical points satisfying certain local conditions, we prove the existence of two-peak solutions.

Interior Peak Solutions for a Semilinear Dirichlet Problem
AxiomsIn this paper, we consider the semilinear Dirichlet problem (Pε):−Δu+V(x)u=un+2n−2−ε, u>0 in Ω, u=0 on ∂Ω, where Ω is a bounded regular domain in Rn, n≥4, ε is a small positive parameter, and V is a non-constant positive C2-function on Ω¯.

Sign-changing two-peak solutions for an elliptic free boundary problem related to confined plasmas
Advances in Nonlinear Analysis, 2018 By a perturbative argument, we construct solutions for a plasma-type problem with two opposite-signed sharp peaks at levels 1 and -γ{-\gamma}, respectively, where ...

Multi-peak Solutions of a Nonlinear Schrödinger Equation with Magnetic Fields
Advanced Nonlinear Studies, 2014 Abstract In this paper, we study a nonlinear Schrödinger equation with magnetic fields involving subcritical growth. Applying the finite reduction method, we prove that the equation has multi-peak solutions under some suitable conditions which are given in section 1.

Solutions with peaks for a coagulation-fragmentation equation. Part II: Aggregation in peaks [PDF]
Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2021 The aim of this two-part paper is to investigate the stability properties of a special class of solutions to a coagulation-fragmentation equation. We assume that the coagulation kernel is close to the diagonal kernel, and that the fragmentation kernel is diagonal.

Index-Based Solutions for Efficient Density Peak Clustering [PDF]
IEEE Transactions on Knowledge and Data Engineering, 2022 Density Peak Clustering (DPC), a popular density-based clustering approach, has received considerable attention from the research community primarily due to its simplicity and fewer-parameter requirement. However, the resultant clusters obtained using DPC are influenced by the sensitive parameter $d_c$, which depends on data distribution and ...
