| Outline of Final Research Achievements |
It is very important to pursue mathematical study for Partial Differential Equations which describe various phenomena arising in natural sciences such as Physics. However, since the behavior of solutions of wave equation, a typical example of hyperbolic equation, and heat equation, a typical example of parabolic equation, is quite different to each other, the method of study and the group of researchers are both separated. Based on the fact that wave equation with strong dissipation acquires some parabolicity which was detected by research representative, we studied some abstract hyperbolic equation with strong dissipation and clarified the mechanism of acquiring the parabolicity and revealed the hierarchical structure underlying between hyperbolicity and parabolicity.
