Balances for fixed points of primitive substitutions
An in!nite word de!ned over a !nite alphabet A is balanced if for any pair (!;!′) of factors of the same length and for any letter a in the alphabet ‖!|a − |!|a|6 1; where |!|a denotes the number of occurrences of the letter a in the word !. In this paper, we generalize this notion and introduce a measure of balance for an in!nite sequence. In the case of !xed points of primitive substitutions,...
متن کامل2 00 7 Return Words in Fixed Points of Substitutions
We present three simple ideas which enable to determine easily the number of return words in some infinite words. Using these ideas, we give a new and very short proof of the fact that each factor of an Arnoux-Rauzy word of order m has exactly m return words. We describe the structure of return words for the Thue-Morse sequence and focus on infinite words which are associated to simple Parry nu...
متن کاملFixed Points Theorems with respect to \fuzzy w-distance
In this paper, we shall introduce the fuzzyw-distance, then prove a common fixed point theorem with respectto fuzzy w-distance for two mappings under the condition ofweakly compatible in complete fuzzy metric spaces.
متن کاملEffective actions with fixed points.
The specific form of the constant term in the asymptotic expansion of the heat-kernel on an axially-symmetric space with a codimension two fixed-point set of conical singularities is used to determine the conformal change of the effective action in four dimensions. Another
متن کاملDiagonal arguments and fixed points
A universal schema for diagonalization was popularized by N.S. Yanofsky (2003), based on a pioneering work of F.W. Lawvere (1969), in which the existence of a (diagonolized-out and contradictory) object implies the existence of a fixed-point for a certain function. It was shown that many self-referential paradoxes and diagonally proved theorems can fit in that schema. Here, we fi...
