Sažetak:
If G = (V, E) is a molecular graph, and du is the degree of its vertex u , then the d2 and first and second Zagreb indices are du dv , respectively. These molecular u u∈V uv∈E structure descriptors, introduced in the 1970s, have been much studied. Yet, a number of their properties, that seem to be have evaded attention so far, are established in this work for the first time. Also a more recent degree–based descriptor, the geometric–arithmetic √ du dv /[(du + dv )/2] , is analyzed. It is demonstrated that instead of index, equal to uv∈E the ratio of geometric and arithmetic means, almost any other means could be used.
