Topological Indices of Semigraph

Topological indices of different molecular structures has been widely studied since last many decades. These indices are treated as a score function which maps a structure to a real numerical value and this value can be used as a descriptor of the structure which helps to study the structure and under its characteristics. Topological indices are been defined in many ways based on distances between nodes, degree of a node .In this paper we will be discuss various types of topological indices of some special classes of semigraphs. Here we will use the adjacent degree of end vertices to define these indices. Also in this paper we will find the generalised formula of these indices for complete Semigraph and
