CONJUGACIES FOR TILING DYNAMICAL SYSTEMS
(784K, postscript)

ABSTRACT.  We consider tiling dynamical systems and topological conjugacies 
between them. For substitution tiling systems under rather general 
conditions, including the Penrose and pinwheel systems, we show that 
conjugacies are generalized sliding block codes, and that the 
substitution is invertible.
