Lokesha, Sushmitha Jain and M. Manjunath Department of Studies in Mathematics Vijayanagara Sri Krishnadevaraya University Ballari, India e-mail: v.lokesha@gmail.com sushmithajain9@gmail.com manju3479@gmail.com Abstract The study of discrete adriatic indices is currently one of the most active research fields in chemical graph theory. The present article focusing the investigation on generalized version of Dutch windmill graph of some graph operators using adriatic indices. 1. Introduction and Preliminaries A topological index is a numerical number which is used to predict various physical, biological and chemical activities such as surface tension, density, melting point, a heat of evaporation and the boiling point of the involved chemical compound. Moreover, it studies quantitative structure- activity relationships (QSAR) and structure-property relationships (QSPR) that are used in the subject of cheminformatics [3, 10, 18].
