In this paper, we investigate the existence and the bifurcation phenomenon of positive solutions for three class of quasilinear elliptic problems.In chapter 1, we establish the existence and the bifurcation phenomenon of posi-tive solutions for a class of p-Kirchhoff type equationwheren/2<p<n,0<s<2p-n/n-p,mes(?)<1.In chapter 2, we investigate the existence of entire solution for the following quasilinear elliptic equation where h(x)>0, b(x)> 0.In chapter 3, we consider the entire solution of the following singular quasilinear elliptic equation... |
