| Outline of Final Research Achievements |
We investigated the behaviour of solutions of mathematical models describing the reproduction of pathogen in vivo and describing the spread of infectious disease. Our main results concern construction of Lyapunov functions. Once a Lyapunov function is obtained, we can know the behaviour of the solution since the solution moves to the direction in which the value of the function decreases. Unfortunately, general methods of constructing a Lyapunov function are unknown, and applications of Lyapunov functions are restricted to some models. In our studies, we used a method to construct a Lyapunov function by using a known Lyapunov function for another model.
