Recent Advance in Chemical Graph Theory

We present the recent advance in chemical graph theory. The whole contexts can be divided into five parts: first we determine the eccentric version indices of bacterial hypertrees; then the degree based indices of star of David and hexagonal cage networks are discussed; the third we obtain the degree based indices of a type of benzenoid systems: jagged-rectangle; the fourth the degree based indices of poly honeycomb networks are calculated; at last we yield the distance based indices of some edge deleted graphs.
