===== Bipartite adjacency matrix =====
==== Set ====
| @#55CCEE: context     | @#55CCEE: $n_X,n_Y\in\mathbb N$ | 

| @#FFBB00: definiendum | @#FFBB00: $ B \in \mathrm{it}(n_X,n_Y) $ |

| @#55EE55: postulate   | @#55EE55: $ B \in \mathrm{Matrix}(n_X,n_Y,\mathbb N) $ |

==== Discussion ====
If the indices $i,j$ label two vertices belonging to the partitions $X,Y$ of a finite [[bipartite graph]], respectively, then the value $B_{ij}$ determines the number of edges joining them.
