Let be a simple and undirected graph with vertex set . A set is called a dominating set of if every vertex
outside is adjacent to at least one vertex of . For any integer , a dominating set is called a -adjacency
dominating set of if the induced subgraph contains at least one vertex of degree at most . The minimum
cardinality of a - adjacency dominating set of is called the - adjacency domination number of that is
denoted by . In this paper, the study of - adjacency domination in graphs is initiated, and exact values and
some bounds on the - adjacency domination number of a given graph are presented. Furthermore, it is
shown that there is a polynomial-time algorithm that computes the -adjacency domination number of a
given tree. Moreover, it is proven that the decision problem associated to the -adjacency domination is
NP-complete for bipartite graphs.
