A Study of Broline-Crowe-Isaacs Matrices of Polygon Dissections

The work realized by the authors of [4], [5] and [6] associates a non-negative matrix with positive integers entries to each dissection of a polygon. In the particular case of triangulations, these matrices called BCI-matrices here contain valuable information of their frieze patterns, a concept introduced by Coxeter and Conway. This paper is con cerned with the algebraic manipulation and properties of these matrices which are derived from operations acting on dissections. KCI Citation Count: 0
