Dear Colleagues, Carbon allotropes are basically distinguished by the way in which carbon atoms are linked to each other, forming different types of networks (graphs) of carbon atoms. Different structures are builds with sp2-hybridized carbon atoms like PAHs, graphite, nanotubes, nanocones, nanohorns, and … WebIn order to compute the number of -cycles, all closed -walks that are not cycles must be subtracted. One would think that by analogy with the matching-generating polynomial , independence polynomial, etc., a cycle polynomial whose coefficients are the numbers of cycles of length would be defined.
