**Abstract**

This project aims to develop models of random walkers on the lattice. Characteristic quantities are obtained, such as the diffusion coefficient, the first and second moment of the distributions. Another important point is to construct phase diagrams in the generalization of related models and their application to real systems such as economic phenomena and Alzheimer's disease. (AU)
