Hodge decompositions of Loday Symbols in K-theory and cyclic homology, by Susan C. Geller and Charles A. Weibel

Abstract: We study the decompositions of K-theory and cyclic homology induced by lambda operations, and in particular the decomposition of the Loday symbols <<x,y,...,z>>. Except in special cases, these Loday symbols do not have pure Hodge index. Our calculations disprove conjectures of Beilinson and Soulé in K-theory, and of Gerstenhaber and Schack in Hochschild homology.
