Abstract :
The rst leap Zagreb index LM1 of a (molecular) graph, is the sum of squares of the second degrees
of vertices (number of their second neighbors), and the second leap Zagreb index LM2 is the sum of
the products of the second degrees of pairs of adjacent vertices, and the third leap Zagreb index LM3
is the sum of the product of the degree and second degree of the vertices. In this paper, we determine
the rst, second and third leap Zagreb indices of some graph operations.
