Multiplicity and Concentration of Solutions for Choquard Equation with Competing Potentials via Pseudo-Index Theory ()
ABSTRACT
In this paper, we consider the following nonlinear Choquard equation -ε
2Δw+V(x)w=ε
-θ(
Y1(w)+
Y2(w)), where ε>0, N>2,
Y1(w):=
W1(x)[I
θ*(
W1|w|
p)]|w|
p-2w,
Y2(w):=
W2(x)[I
θ*(
W2|w|
q)]|w|
q-2w, I
θ is the Riesz potential with order Θ∈(0,N),
and infRNWi>0, i=1,2. By imposing suitable assumptions to V(x),
Wi(x), i=1,2, we establish the multiplicity of semiclassical solutions by using pseudo-index theory and the existence of groundstate solutions by Nehari method. Moreover, the convergence and concentration of the positive groundstate solution are discussed.
