Corona Product of Three Molecular Descriptors

In this manuscript, we investigate the behavior of S index, Y and S coindices under the different corona products of graphs. We consider the corona product of two simple connected graphs A and B, and derived closed-form expressions for the S index, Y and S coindices of graphs in terms of the indices and coindices and structural properties of the constituent graphs. This analysis generalizes previous results and provides new insights into the additive and multiplicative behavior of S index, Y and S coindices under graph operations.
