The Existence Of Multiple Solutions For Two Classes Of Semilinear Elliptic Equations

In this thesis, we are devoted to the study of the existence and multiplicity results of problem:where 0 ∈ Ω and Ω(?) R~N(N≥ 3) is a bounded domain with smooth boundary,0≤μ<μ|-=((N- 2)/2)~2; here μ|- is the best constant in the Hardy inequality0
