### Abstract

The first, second and third leap Zagreb indices are the sum of squares of second degrees of vertices of G, the sum of products of second degrees of pairs of adjacent vertices in G and the sum of products of first and second degrees of vertices of G, respectively. In this Paper We obtained the formal of leap Zagreb Indices for the central graph of graph. Also We compute the the first, second and third leap Zagreb for the central graph of some standard graph.
