| Outline of Final Research Achievements |
We constructed a mathematical model for brewing process of Japanese Sake by using partial differential equations with focusing thermal reactions, chemical reactions, and biological phenomena. Our model includes some factors that depends upon each fermenting stages (there are 5 fermenting stages). Moreover, our model corresponds to the mathematical problem so-called "quasi-variational inequality". Throughout our study, we got the existence of solutions for our mathematical model of 1st fermenting stage (the stage of culturing Koji). Furthermore, we analyze some relating mathematical problems, and proved solvability results for a certain abstract evolution equation of quasi-variational inequality type.
