An Upper Bound on the Number of States for a Strongly Universal Hyperbolic Cellular Automaton on the Pentagrid
نویسنده
چکیده
− In this paper, following the way opened by a previous paper deposited on arXiv, we give an upper bound to the number of states for a hyperbolic cellular automaton in the pentagrid. Indeed, we prove that there is a hyperbolic cellular automaton which is rotation invariant and whose halting problem is undecidable and which has 9 states.

A Weakly Universal Cellular Automaton in the Pentagrid with Five States
In this paper, we construct a cellular automaton on the pentagrid which is planar, weakly universal and which have five states only. This result much improves the best result which was with nine states.
متن کاملA weakly universal cellular automaton in the hyperbolic 3D space with three states
In this paper, we follow the track of previous papers by the same author, with various collaborators or alone, see [2, 7, 13, 14, 10, 9], which make use of the same basic model, the railway model, see [16, 5, 9]. In order to be within the space constraint for the paper, we just refer to the above mentioned paper both for what is the railway model and for what is hyperbolic geometrY. For the lat...
متن کاملA weakly universal cellular automaton on the pentagrid with two states
In this paper, we prove that there is a weakly universal cellular automaton on the pentagrid with two states. This paper improves in some sense a previous result with three states. Both results make use of \textit{\`a la Moore} neighbourhood. However, the result with three states is rotation invariant while that with two states is not. In both cases, at each step of the computation, the set of ...
متن کاملAbout Strongly Universal Cellular Automata
In this paper, we construct a strongly universal cellular automaton on the line with 11 states and the standard neighbourhood. We embed this construction into several tilings of the hyperbolic plane and of the hyperbolic 3D space giving rise to strongly universal cellular automata with 10 states.
متن کاملOn a Characterization of Cellular Automata in Tilings of the Hyperbolic Plane
In this paper, we look at the extension of Hedlund’s characterization of cellular automata to the case of cellular automata in the hyperbolic plane. This requires an additional condition. The new theorem is proved with full details in the case of the pentagrid and in the case of the ternary heptagrid and enough indications to show that it holds also on the grids {p, q} of the hyperbolic plane.
