We illustrate how the dynamical properties of any Linear CA over (Z/mZ)^n are hidden inside the characteristic polynomial of its defining matrix, namely, a polynomial of degree n in the indeterminate t and with Laurent polynomials over Z/mZ as coefficients. In particular, we exhibit an easy to check algebraic characterization of…

Cellular Automata (CA) gained some interest from cryptographers in the 80s after Wolfram proposed to use rule 30 for generating pseudorandom numbers. Then, after Wolfram’s generator was shown to be vulnerable in the 90s, the research trend of CA-based cryptography apparently faded away in the cryptography community. Indeed, most of…

Logical modelling is a popular mathematical framework for assessing the behaviour of regulatory and signalling networks. Despite its qualitative nature, it allows disclosing crucial dynamical properties. Here we briefly present the formalism and new challenges involved when building models and analysing them. We then introduce recent methodological advances for model…

The process of influence and opinion dynamics is predominant in many kinds of real-life situations involving agents’ interactions. This phenomenon is extensively analyzed in different fields and with the help of various methods and tools. Network analysis is particularly suitable for the study of influence and opinion formation. The aim…
