本文研究了Choquard方程-Δ u+(λ a(x)+ 1)u=\displaystyle\big(1)的多凸解的存在性|X|联系我们|u| ^ p\big)|u| ^ p-2 u in I,I,I,R^ 3,-Δ u+(λ a(x)+ 1)u=(1| X| μ∗| u| p)的范围内|u|其中μ ∈(0,3),p ∈(2,6-μ)μ∈(0,3),p ∈(2,6-μ),λ λ为正参数,且非负连续函数a(x)有一个势阱Ω:= int(a^-1(0))Ω:= int(a-1(0)),该势阱具有k个不相交的有界分支Ω:= j= 1^ k Ω j Ω:= j= 1 k Ω j.证明了当参数λ λ足够大时,方程至少有2^ k-1 2 k-1个多凸解.
In this paper we study the existence of multi-bump solutions for the following Choquard equation-Δ u+(λ a (x)+ 1) u=\displaystyle\big (1| x|^ μ*| u|^ p\big)| u|^ p-2 u in\,\,\, R^ 3,-Δ u+(λ a (x)+ 1) u=(1| x| μ∗| u| p)| u| p-2 u in R 3, where μ ∈ (0, 3), p ∈ (2, 6-μ) μ∈(0, 3), p∈(2, 6-μ), λ λ is a positive parameter and the nonnegative continuous function a (x) has a potential well Ω:= int (a^-1 (0)) Ω:= int (a-1 (0)) which possesses k disjoint bounded components Ω:= ∪ _ j= 1^ k Ω _j Ω:=∪ j= 1 k Ω j. We prove that if the parameter λ λ is large enough, then the equation has at least 2^ k-1 2 k-1 multi-bump solutions.
