Abstract: We classify positive radial entire solutions of a class of quasilinear elliptic equation including the usual Laplace, m-Laplace, and k-Hessian operators in the space of radial functions. The intersection properties of positive entire solutions were studied via PDE arguments. We also present a global bifurcation diagram of positive radial solutions of the Dirichlet problem with polynomial nonlinearity. This is based on a joint work with Z.M.Guo.
