| Outline of Final Research Achievements |
I studied the structure of the graph of the functional for mean fields of equilibrium vortices in terms of the Hamiltonian of vortices. A mean field is a critical point of a functional and steady vortices form a critical point of a function (Hamiltonian). The main result is to determine the inequalities that estimate the Morse index of the mean field, which is sufficiently close to blow-up, in terms of the Morse index of the steady vortices, when a blow-up sequence of mean fields and the steady vortices in its blow-up limit are given. The mean fields that I consider are solutions of the Gel’fand problem, which comes from the functional that is rather simplified one from the usual free energy functional for mean fields. Our conclusion, however, generalize the known result that treats one point blow-up cases only to general many points blow-up cases. I also give some fine behaviors of linearized eigenvalues of Gel’fand problem.
