| Research Abstract |
We investigate mathematical properties and structures of solutions to the model equations describing the superconductivity and Bose-Einstein condensation, which are typical macroscopic quantum phenomena. We obtained mathematical results on the bifurcation structure and the characteristic dynamics for the model equations such as the Ginzburg-Landau equations and other related equations.
