Abstract: This paper deals with certain aspects of a conjecture made by B. Kostant in 1983 relating the Coxeter number to the occurrence of the simple finite groups in simple complex Lie groups. A unified approach to Kostant's conjecture that yields very general results for the rank two case is presented.
