The link between the equation $b(b+a)-a^2=0$ concerning the side $b$ and the diagonal $a$ of a regular pentagon and the {\it Cassini identity} $F_{i}F_{i+2}-F_{i+1}^2=(-1)^{i}$, concerning three consecutive Fibonacci numbers, is very strong. In this

In this paper, we characterize by lexicographic order all finite Sturmian and episturmian words, i.e., all (finite) factors of such infinite words. Consequently, we obtain a characterization of infinite episturmian words in a "wide sense" (episturmia

A result of a student of Erdos is well known: for every integer $n\ge 1$, each subset of $I(2n)=\{1,2,\dots,n+1,n+2,\dots,2n \}$ having size $n+1$ contains at least two distinct elements of which the smaller divides the larger. This is proved using t
