Infinite many normalized solutions for Schrodinger-Bopp-Podolsky systems with singular coefficient and critical growth

Zixing Cai, Li Wang

Abstract:
This article studies normalized solutions for the critical Schrodinger-Bopp-Podolsky system with singular coefficient and critical growth, $$\displaylines{ -\Delta u +\lambda u = \phi u + \dfrac{|u|^{s-2}u}{|x|^q} + ( I_{\alpha}*|u|^{2_\alpha^*})|u|^{2_\alpha^*-2}u, \quad x \in \mathbb{R}^3, \cr -\Delta \phi+d^2\Delta ^2\phi = 4\pi u^2, \quad x \in \mathbb{R}^3 }$$ under the mass constraint $$ \int_{\mathbb{R}^3} |u|^2 dx = a^2, $$ where \(a >0\) is a constant, \( 0< \alpha < 3\), \( 0 < q < 2< s < 10/3\) satisfying \( q+\frac{s}{2} < 3 < q+\frac{3s}{2}< 5 \), and $$ I_\alpha(x) = \frac{A_\alpha}{|x|^{3 - \alpha}}, \quad \text{with } A_\alpha = \frac{\Gamma\big(\frac{3 - \alpha}{2}\big)}{2^\alpha \pi^{3/2}\Gamma(\frac{\alpha}{2})} $$ which is the Riesz potential. Here \( 2^*_{\alpha} = 3+\alpha\) is the Hardy Littlewood Sobolev upper critical exponent. We establish the existence of multiple normalized solutions by using truncation techniques and topological genus theory. To address the non-compactness of the energy functional caused by singular and critical growth, we use the concentration-compactness principle. This paper also presents results regarding the stabilization of the orbit and the asymptotic behavior of the ground-state solution as \(d\to 0\).
