Dynamical systems with double recursion are undecidable
Mihai Prunescu
A primitive type of two-dimensional dynamic system is introduced. It is shown that there is no decision procedure able to answer if such a dynamical system is ultimately zero.

Self-similar carpets over finite fields
Mihai Prunescu
Some linear dynamical systems over finite fields are studied and the self-similar character of their development is proved. Connections with aperiodic tilings, Delanoy numbers and…
