A Hopf-Algebra Approach to Inner Plethysm

Jean-Yves Thibon


We use the Hopf algebra structure of the algebra of symmetric functions to study the Adams operators of the complex representation rings of symmetric groups, and we give new proofs of all of Littlewood's formulas for inner plethysm. We also study the Adams operations for orthogonal and symplectic group characters. (C) 1994 Academic Press, Inc.
