Outline of Final Research Achievements |
I studied the structure of the positive solutions of nonlinear elliptic PDEs. In particular, I studied bifurcation diagrams. Mainly, two results were obtained. I proved that the imperfect bifurcation occurs in the bifurcation diagram of the positive solutions of the Gel'fand problem when the domain is perturbed. I almost completely classified the bifurcation diagrams of the positive radial solutions of the Dirichlet problem of supercritical elliptic PDEs in a ball. I obtained partial results about the bifurcation diagram of the positive radial solutions of the Neumann problem of the supercritical scalar field equation in a ball.
