Existence of bound state solutions for degenerate singular perturbation problems with sign-changing potentials
In this article, we study the degenerate singular perturbation problems $$displaylines{ -varepsilon^2hbox{div}(|x|^{-2a}abla u)+|x|^{-2(a+1)}V(x)u = |x|^{-b2^*(a,b)}g(x,u),cr -hbox{div}(|x|^{-2a}abla u)+ lambda |x|^{-2(a+1)}V(x)u = |x|^{-b2^*(a,b)}g(x,u), }$$ for $varepsilon$ small and $lambd...
