An infinite word is S-automatic if, for all n 0, its (n+1)st letter is the output of a deterministic automaton fed with the representation of n in the numeration system S. In this...
Solutions of recursive program schemes over a given signature were characterized by Bruno Courcelle as precisely the context-free (or algebraic) -trees. These are the finite and ...
A stream X-machine is a type of extended finite state machine with an associated development approach that consists of building a system from a set of trusted components. One of th...
Timed automata are governed by an idealized semantics that assumes a perfectly precise behavior of the clocks. The traditional semantics is not robust because the slightest perturb...

The rules of "Bulgarian solitaire" are considered as an operation on the set of partitions to induce a finite dynamical system. We focus on partitions with no preimage u...
