A Kirchhoff equation type with memory term competing a logarithmic source is considered. By using potential well theory, we obtained the global existence of solution for initial data in stability set created from Nehari Manifold and prove blow up results instability set.

We consider the cubic nonlinear Schr\"{o}dinger equation on star graph with Kirchhoff boundary condition. prove modified scattering for final state problem and initial value problem. Moreover, we also failure of power-type long-range nonlinearities. These results are extension NLS one dimensional Euclidean space.

In this paper‎, ‎we consider the following Kirchhoff-type equations‎: ‎$-‎left(a+bint_{mathbb{R}^{3}}|nabla u|^{2}right)Delta u+V(x) u=lambda$ $f(x,u)+u^{5}‎, ‎quad mbox{in }mathbb{R}^{3},$ ‎$u(x)>0‎, ‎quad mbox{in }mathbb{R}^{3},$ ‎$uin H^{1}(mathbb{R}^{3})‎ ,‎$ ‎ ‎‎‎where $a,b>0$ are constants and $lambda$ is a positive parameter‎. ‎The aim of this paper is to study the existence of positive ...

The detailed assumptions on K , r , β, and a are given in (3), (4) and Condition 1 below. For K = K (s) = c1 + c2s (c1, c2 > 0) and p = r = β = 2, we get the famo...
