RT journal article T1 The total co-independent domination number of some graph operations A1 Cabrera Martínez, Abel A1 Cabrera García, Suitberto A1 Peterin, Iztok A1 González Yero, Ismael A2 Matemáticas AB A set D of vertices of a graph G is a total dominating set if every vertex of G is adjacent to at least one vertex of D. The total dominating set D is called a total co-independent dominating set if the subgraph induced by V (G)- D is edgeless. The minimum cardinality among all total co-independent dominating sets of G is the total co-independent domination number of G. In this article we study the total co-independent domination number of the join, strong, lexicographic, direct and rooted products of graphs PB UNION MATEMATICA ARGENTINA SN 1669-9637 YR 2022 FD 2022-06 LK http://hdl.handle.net/10498/28809 UL http://hdl.handle.net/10498/28809 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 12-nov-2026
