摘要：
For a molecular graph G, the F-index or forgotten topological index is defined as the sum of cubes of degree of all vertices of the graph and the hyper-Zagreb index is equal to the sum of square of sum of degree of all adjacent vertices of the graph. In this paper, we obtain F-index, hyper-Zagreb index and their coindices of F-tensor products (four new tensor products based on transformations of a graph) of graphs and their complements.
