Normalized solutions for a fractional Schrödinger-Poisson system with critical growth
arxiv(2024)
摘要
In this paper, we study the fractional critical Schrödinger-Poisson
system
(-Δ)^su +λϕ u= α
u+μ|u|^q-2u+|u|^2^*_s-2u, ℝ^3,
(-Δ)^tϕ=u^2, ℝ^3,
having
prescribed mass
∫_ℝ^3 |u|^2dx=a^2,
where s, t ∈ (0, 1)
satisfies 2s+2t > 3, q∈(2,2^*_s), a>0 and λ,μ>0 parameters and
α∈ℝ is an undetermined parameter. Under the
L^2-subcritical perturbation q∈ (2, 2+4s/3), we derive the
existence of multiple normalized solutions by means of the truncation
technique, concentration-compactness principle and the genus theory. For the
L^2-supercritical perturbation q∈ (2+4s/3, 2^*_s), by applying
the constrain variational methods and the mountain pass theorem, we show the
existence of positive normalized ground state solutions.
