SOME COMBINATORIAL PROPERTIES OF n-COLOUR COMPOSITIONS

Print ISSN: 0972-7752

Abstract

A connection between a special kind of walks in the XY -plane studied by J.H. van Lint and R.M. Wilson [7] and n-colour compositions introduced recently by A.K. Agarwal [1] is shown. This leads to several new combinatorial properties of the walks and also gives a new binomial identity with its combinatorial interpretation.

Keywords and Phrases
