The following results are achieved under this grant.
(1) Study on the applications of “L-infinity Energy Method” to nonlinear partial differential equations:
We applied L-infinity Energy Method to the system of parabolic equations which describes a diffusion-convection prey-predator model which takes into account of the hysteresis effects. Because of the strong nonlinearity of this system, we needed to improve some tools to establish a priori estimates for the L-infinity norm of solutions, by which we could ameliorate previous studies.
(2) Study on complex Ginzburg-Landau equations (CGLE):
(i) For the non-dissipative system in bounded domains, we proved the existence and the uniqueness of time-local solutions for CGLE in H^1-space.
(ii) We analyzed the finite-time blow-up of solutions of CGLE.
The previous studies dealt with the case where the energy of the initial data is negative in the whole domain.
We developed a new method to treat the case where the energy of the initial data is positive in general domains.
(3) Study on the mathematical analysis for the mitochondrial swelling model:
We analyzed this model with Robin-type boundary conditions, which describes well the real situation of mitochondria in cells. We showed the well posedness of the system as well as the asymptotic behavior of solutions.
