Localized nodal solutions for semiclassical Choquard equations with critical growth
Bo Zhang, Wei Zhang
Abstract:
In this article, we study the existence of localized nodal solutions for
semiclassical Choquard equation with critical growth
$$
\epsilon^2 \Delta v +V(x)v
= \epsilon^{\alphaN}\Big(\int_{R^N}
\frac{v(y)^{2_\alpha^*}}{xy^{\alpha}}\,dy\Big) v^{2_\alpha^*2}v
+\thetav^{q2}v,\; x \in R^N,
$$
where \(\theta>0\), \(N\geq 3\),
\(0< \alpha<\min \{4,N1\},\max\{2,2^*1\}< q< 2^*\), \(2_\alpha^*= \frac{2N\alpha}{N2}\), \(V\) is a bounded function.
By the perturbation method and the method of invariant sets of descending flow,
we establish for small \(\epsilon\) the existence of a sequence of localized
nodal solutions concentrating near a given local minimum point of the potential
function \(V\).
