Math. Comput. 215, No. 12, 4263-4271 (2010).} \itemab Summary: This paper presents a method for establishing relations between entropy-based measures applied to graphs. A special class of relations called implicit information inequalities or implicit entropy bounds is developed. A number of entropy-based measures of the structural information content of a graph have been developed over the past several decades, but little attention has been paid to relations among these measures. The research reported here aims to remedy this deficiency. \itemrv{~} \itemcc{} \itemut{graphs; entropy; structural information content; inequalities; information theory} \itemli{doi:10.1016/j.amc.2009.12.051} \end
