#1732787578929264-410: The area of combinatorial mathematics, Snapper extended de Bruijn ’s theory of the cycle index of a finite group to that of an arbitrary permutation representation. A subsequent paper coauthored with Arunas Rudvalis extended this cycle index to a generalized cycle index of a permutation representation paired with a class function. They then obtained the theorem of Frobenius that every simple character of

An early sequence of papers extended the Steinitz field theory to completely primary rings using ideas from the work of Krull . During his visits at Princeton and Harvard, Snapper studied algebraic geometry and the homological and sheaf-theoretic methods of Serre and Grothendieck . Later he applied those methods in several important papers on
