On the Existence of Infinitely Many Solutions for Some Nonlinear Elliptic Systems with Perturbations
HU Ye-xin(Applied Mathematics Deparment,Shanghai University of Finance and Economics,Shanghai 200433,China)
Abstract:
In this paper,we study the existence of infinitely many solutions for a class of non-linear elliptic systems governed by two Laplacian operators involving perturbations under some conditions.(-△u=∣u∣α-1∣υ∣β+1u+f,x∈Ω,-△υ=∣u∣α+1∣υ∣β-1υ+g,x∈Ω,u(x)+ υ(x)=0,x∈(e)Ω,)where-△u:=-div(▽u),(u,υ)∈E:=H10(Ω)× H10(Ω),(f,g)∈E^*.[著者文摘]
