Abstract
A vertex set S of a simple finite graph \(G=(V;E)\) is said to be an independent set if there is no edge between any pair of vertices of S and a dominating set if for any \(v\in V-S\), \(uv\in E\) for some \(u\in S\). If S is both independent and dominating in G, then S is an independent dominating set. Let i(G) denote the cardinality of a minimum independent dominating set of G. Set \(b_i(G)=\min \{|E'|~: E'\subseteq E, i(G)<i(G-E')\}\), which we define as an independent bondage number of G. We initiate the study on properties of \(b_i(G)\) and present some upper and lower bounds on \(b_i(G)\) for some special classes of graphs. Further research problems will be proposed.
