Pere Mumbrú (Barcelona, 1955, Premià de Dalt, 2005) was a global personality who became interested in different life science and culture. He was doing active research in the field of Teaching Mathematics and in Discrete Dynamical Systems. In this last field, his interests and publications were distributed in the following topics:
- Symbolic dynamics
- Topological entropy
- Models with minimal dynamics on trees and graphs
- Characterization of the set of periods of continuous tree
Pere was an excellent mathematician. He had deep and creative thinking, a great capacity for work, and contagious enthusiasm. His contributions were very important to understand phenomena related to chaotic dynamics in one-dimensional spaces. In this field, he developed a unique insight that helped many of his colleagues.
Pere also had an intellectual side. He was a man deeply interested in everything going on around them. Lover of reading, cinema, and art in all its manifestations. Interested in psychology, education, politics,... He maintained a discreet but constant political activity in his town, away from political parties but spending part of his free time influencing the political life of his people.
