ADJACENCY MATRIX OF SIGNED SEMIGRAPHS
Surajit Kr. Nath and Ardhendu Kumar Nandi
|
Abstract: We introduce the adjacency matrix for both the e-signed and v-signed semigraphs. A necessary and sufficient condition for a matrix to be e-signed (v-signed) is given. Also, we obtain some properties of adjacency matrix associated with e-signed and v-signed semigraphs. |
Keywords and phrases: semigraphs, e-signed semigraph, v-signed semigraph, adjacency matrix of a signed semigraph, signed semigraphical matrix.
