主 题:nonlinear Kirchhoff problem Lyapunov-Schmidt reduction positive solutions level set
摘 要:This paper deals with the existence of positive solutions to the following nonlinear Kirchhoff equation with perturbed external source terms:{−(a+b∫_(R^(3))|∇u|^(2)dx)Δu+V(x)u=Q(x)u^(p)+εf(x),u0,x∈R^(3),u∈H^(1)(R^(3)).Here a,b are positive constants,V(x),Q(x)are positive radial potentials,10 is a small parameter,f(x)is an external source term in L^(2)(R^(3))∩L^(∞)(R^(3)).
