The Todd character and the integrality theorem for the Chern character
In [5] the authors introduced a homomorphism called the Todd character, relating complex bordism homology theory to rational homology.Specifically, the Todd character is a family of homomorphisms th" MU,(X) @ =0 the component morphisms being denoted by th._k M U. X -Hn_k X Q By analogy with the Chern character …
