### Universality of Causal Graph Dynamics

Causal Graph Dynamics generalize Cellular Automata, extending them to bounded degree, time varying graphs. The dynamics rewrite the graph at each time step with respect to two physics-like symmetries: causality (bounded speed of information) and homogeneity (the rewriting acts the same everywhere on the graph, at every time step). Universality is the ability of simulating every other instances of another (or the same) model of computation. In this talk, we will present different ways to achieve universality for the model of CGD. More particularly, we will present the construction of an intrinsically universal and uniform family of CGD.
