Inverse Domination Number and Inverse Total Domination of Sierpinski Star Graph (Published)

Given a graph  consisting of the set of vertices  and the set of edges . For example,  is a domination set of graph  with minimum cardinality, if  contains a domination set , then  is called the inverse domination set of graph . The minimum cardinality of the inverse domination set of the graph  is called the inverse domination number, denoted by . If  is the total domination set of the graph  with minimal cardinality, and  contains the total domination set , then  is called the inverse total domination set of the graph . The minimum cardinality of the inverse total domination set of the graph  is called the inverse total domination number, denoted by . This paper discusses the inverse domination and the inverse total domination on the Sierpinski Star graph , obtained the inverse domination number  for  and  for   and the inverse total domination number  for .
