For .f a set of graphs, define the bounded chromatic number Xb(&) (resp. the bounded path chromatic number Xpfë) ) to be the minimum number of colors c for which there exists a constant M such that every graph G € 2? can be vertex c-colored so that all but M vertices of G are properly colored (resp. the length of the longest monochromatic path in G is at most M ). For 3? the set of toroidal gra...
Chemical graphs, as other ones, are regular if all their vertices have the same degree. Otherwise, they are irregular, and it is of interest to measure their irregularity both for descriptive purposes and for QSAR/QSPR studies. Three indices have been proposed in the literature for that purpose: those of Collatz-Sinogowitz, of Albertson, and of Bell's variance of degrees. We study their propert...
