It is well-known that cellular automata can be characterized as the set of translation-invariant continuous functions over a compact metric space; this point of view makes it easy to extend their definition from grids to Cayley graphs. Cayley graphs have a number of useful features: the ability to graphically represent finitely generated group elements and their relations; to name all vertices relative to an origin; and the fact that they have a well-defined notion of translation. We propose a… Expand

Causal dynamics of discrete manifolds
• Mathematics, Computer Science
• NCMA
• 2018
This work formalizes, and proves theorems about, the intuitive idea of a discrete manifold which evolves in time, subject to two natural constraints: the evolution does not propagate information too fast; and it acts everywhere the same. Expand
Reversible causal graph dynamics: invertibility, block representation, vertex-preservation

Causal Graph Dynamics extends Cellular Automata to arbitrary time-varying graphs of bounded degree by proving that the inverse of a causal graph dynamics is a causalGraph dynamics, and that these reversible graph dynamics can be represented as finite-depth circuits of local reversible gates. Expand
Dynamical Triangulation Induced by Quantum Walk
• Physics, Computer Science
• Symmetry
• 2020
Numerical simulations show that the number of triangles and the local curvature grow as $\alpha$ and $\beta$ parametrize the way geometry changes upon the local density of the walker, and that, in the long run, flatness emerges. Expand
Reversibility vs local creation/destruction

This paper obtains reversible local node creation/destruction—in three relaxed settings, whose equivalence the authors prove for robustness, both by theoretical computer science considerations and theoretical physics concerns. Expand

An algorithm is presented which computes online the global transformation of a finite graph in an accretive manner and a local criterion is given for a rule system to extend to a graph global transformation. Expand

Simulations Between Cellular Automata on Cayley Graphs
It is shown that cellular automata on any planar, modular graph are equivalent to cellular automaton on the grid Z2, and interpreted in terms of planar parallel machines. Expand
Causal graph dynamics

• Inf. Comput.
• 2013
The theory of cellular automata is extended to arbitrary, time-varying graphs and the intuitive idea of a labelled graph which evolves in time is formalised - but under the natural constraint that information can only ever be transmitted at a bounded speed, with respect to the distance given by the graph.

Hyperbolic Recognition by Graph Automata
• Computer Science

Graph automata were first introduced by P. Rosenstiehl under the name of intelligent graphs, surely because a network of finite automata is able to know some properties about its own structure, and this hypothesis seems to be absolutely essential for the modelisation of the physical reality. Expand

It is shown that QCA always admit a two-layered block representation, and hence the inverse QCA is again a QCA, a striking result since the property does not hold for classical one-dimensional cellular automata as defined over such finite configurations. Expand
