Abstract

The concept of dominating functions are introduced by Hedetniemi [4] and this concept has been studied extensively in recent years.Unidominating function and unidomination number are new concepts introduced by Anantha Lakshmi [1].She has studied these concepts for some standard graphs. In Discrete Mathematics, Product of graphs occurs naturally as tools in combinatorial constructions. They giverise to important classes of graphs and deep structural problems. Frucht and Harary [3] introduced a new product on two graphs G1and G2,called corona product denoted by . In this paper the concept of total unidominating function and minimaltotalunidominating function for corona product graph W 1,n ʘ K 1,m is discussed anddetermined the total unidomination number andupper totalunidominationnumber for this graph. Also the number of total unidominating functions of minimum weight is found.
