Hochschild homology and truncated cycles

Petter A. Bergh, Yang Han, Dag Madsen (postdoc '08-10)

Abstract: We study algebras having 2-truncated cycles and show that these algebras have infinitely many nonzero Hochschild homology groups. Consequently, algebras of finite global dimension have no 2-truncated cycles and therefore satisfy a higher version of the "no loops conjecture".
