Abstract:
he use of graph theory in many fields of study has increased significantly, especially in
the field of chemical graph theory. Many scholars have been able to explore a range of new
directions in the last few years. A chemical graph is a named graph in which the atoms
of a compound are represented at the vertices, and the edges represent chemical bonds
between atoms. Determining various physical and chemical properties of the molecular
structures under study requires an examination of topological indices. Firstly, we focused
on degree-based topological indices, namely the Randic index, atom bond connectivity in-
dex, geometric arithmetic index, the first and the second Zagreb indices and co-indices,
the first and the second multiple Zagreb indices and co-indices, hyper Zagreb index, for-
gotten index, augmented Zagreb index, Balaban index, redefined Zagreb type indices, of
Palladium Selenide Crystals PdSe2. Further, we gave graphical representations of these in-
dices. These mathematical frameworks might provide a way to study the thermo dynamical
properties of the chemical structure of Palladium Selenide Crystals PdSe2
