摘要:

我们研究了一个涉及混合局部和非局部算子的Choquard方程:[-ε²Δu+ε²s(-Δ)^s u+V(x)u=ε^{μ-2}(1/|x|μ*F(u))f(u)在R²中],其中ε>0,s∈(0,1),0<μ<2,f具有Trudinger-Moser临界指数增长,F(t)=∫₀^t f(τ) dτ。通过变分方法,结合Trudinger-Moser不等式和适应于临界增长和非局部相互作用项的紧致性论证,我们证明了地面态解的存在性,并描述了当ε→0+时解的集中行为。

英文摘要:

We study the Choquard equation involving mixed local and nonlocal operators \[-\varepsilon^{2}Δu+\varepsilon^{2s}(-Δ)^{s}u+V(x)u=\varepsilon^{μ-2}\left(\frac{1}{|x|^μ}*F(u)\right)f(u)\quad \text{in }\R^{2},\] where \(\varepsilon>0\), \(s\in(0,1)\), \(0<μ<2\), \(f\) has Trudinger--Moser critical exponential growth, and \(F(t)=\int_{0}^{t}f(τ)\,dτ\). By variational methods, combined with the Trudinger--Moser inequality and compactness arguments adapted to the critical growth and the nonlocal interaction term, we prove the existence of ground state solutions and describe their concentration behavior as \(\varepsilon\to0^{+}\).
