Abstract
In this paper, we consider the following nonlinear coupled elliptic systems(Aε){âε2Îu+u=μ1u3+βuv2in Ω,âε2Îv+v=μ2v3+βu2vin Ω,u>0,v>0in Ω,âuâν=âvâν=0on âΩ, where ε>0, μ1>0, μ2>0, βâR, and Ω is a bounded domain with smooth boundary in R3. Due to Lyapunov-Schmidt reduction method, we proved that (Aε) has at least O(1ε3|lnâ¡Îµ|) synchronized and segregated vector solutions for ε small enough and some βâR. Moreover, for each mâ(0,3) there exist synchronized and segregated vector solutions for (Aε) with energies in the order of ε3âm. Our result extends the result of Lin, Ni and Wei [20], from the Lin-Ni-Takagi problem to the nonlinear elliptic systems.
