Smart and Sustainable Cities and BuildingsDyck words enumerated by the Catalan numbers. By using Ferrers diagrams associated to Dyck paths, we derive formulas for the enumeration of . with . and . non relatively prime, in terms of Catalan numbers.

Go Muan Sang,Lai Xu,Paul de Vrieze with it, it is also conjectured that binary words have the largest square density. That is, it is sufficient to solve the square conjecture for words over binary alphabet. We solve this subsidiary conjecture affirmatively, or more strongly, we prove the irrelevance of the alphabet size in solving t

We use our decision procedure to reprove some old results about the Tribonacci word from the literature, such as assertions about the occurrences in . of squares, cubes, palindromes,

A Sturmian word . of slope . can be written as a product of these six minimal squares: .. The square root of . is defined to be the word .. We prove that . is also a Sturmian word of slope .. Moreover, we describe how to fi

Second, we prove that any infinite path in the tree has a lot of branching points: the lower density of the set of such points is at least 2/9.
