Evolutionary model with genetics, aging and knowledge
Armando Ticona Bustillos, Paulo Murilo C. de Oliveira
We represent a process of learning by using bit strings, where 1-bits represent the knowledge acquired by individuals. Two ways of learning are considered: individual learning by t…

A general creation-annihilation model with absorbing states
Wellington G. Dantas, Armando Ticona, Jurgen F. Stilck
A one dimensional non-equilibrium stochastic model is proposed where each site of the lattice is occupied by a particle, which may be of type A or B. The time evolution of the mode…

A minimum principle for Lyapunov exponents and a higher-dimensional version of a Theorem of Mane'
Yongluo Cao, Stefano Luzzatto, Isabel Rios
We consider compact invariant sets Λfor C^{1} maps in arbitrary dimension. We prove that if Λcontains no critical points then there exists an invariant probability measure with a L…
