Abstract
Domination in graphs is an emerging area of research in graph theory and in recent years it has been studied extensively. The concept of dominating functions are introduced by Hedetniemi [6] and this concept has been studied extensively in recent years. Unidominating function and unidomination number are new concepts introduced by Anantha Lakshmi [1].She studied these concepts for some standard graphs. A new product on two graphs G1 and G2, called corona product denoted by G1⊙G2, was introduced by Frucht and Harary [3]. The concept signed dominating function of corona product graph Cn⊙Km was studied by Siva Parvathi [8].Aruna [2] has introduced new concepts signed unidominating function and signed upper unidomination number of a graph. In this paper these concepts are studied for corona product graph Cn⊙K(1,m ).
