RETRACTED: On Vertex Degree-Based Topological Indices for Fixed Branching Vertices of Trees (Retracted Article)

The Gourava indices and hyper-Gourava indices are graph invariants, related to the degree of vertices of a graph G. Let T-n,T-b denote the collection of all chemical trees with n vertices where b denotes the number of branching vertices, 1 <= b < (n-2)/2. In the current paper, maximum value for the abovementioned topological indices for different classes T-1(n,b) and T-2(n,b) of T-n,T-b is determined and the corresponding extremal trees are characterized.
