Outline of Final Research Achievements

We have considered some population models living in a habitat. Here, the mortality, the reproduction, and the inflow are supposed to depend on the individual’s size, time and position. In addition, each individual is supposed to spread in the habitat. In this research, as a new framework to analyze such models, we have intended to introduce and develop a theory of abstract partial differential equations. As a basic theory, we have established the existence and uniqueness of solutions, continuous dependence on initial data and positivity of solutions. Also, we have investigated comparison theorem, the dual problem and uniqueness of weak solutions.
