Abstract

This project aims to develop mathematical models for the evolution of genetic code. The labeling of codons to irreducible representations of the simpletic group, the concrete construction of these same representations, a revision of the search for symmetries, the study of non-universal codes and the development of a dynamic model are the central axes of the investigation.
