Abstract
The problem of determining bounds for the chromatics index and the cover index of a multigraph is considered. Results stated include (I) a bound for the cover index which is analogous to the well-known bound for the chromatic index due to Shannon, (II) a bound for the chromatic index (and analogous bound for the cover index) which establishes conjectures by Berge and Bosak.
