The Pascal Rhombus and the Generalized Grand Motzkin Paths

José L. Ramírez

In the present article, we find a closed expression for the entries of the Pascal rhombus. Moreover, we show a relation between the entries of the Pascal rhombus and a family of ge…

A $q$ -analogue of the Biperiodic Fibonacci Sequence

José L. Ramírez, Víctor Sirvent

The Fibonacci sequence has been generalized in many ways. One of them is defined by the relation $t_{n} = a t_{n - 1} + t_{n - 2}$ if $n$ is even, $t_{n} = b t_{n - 1} + t_{n - 2}$ if $n$ is odd, with i…
