Abstract: We establish a general splitting formula for index bundles of families of
Dirac type operators. Among the applications, our result provides a positive answer
to a question of Bismut and Cheeger [BC2].
Introduction
Due to the increasing influence of the topological quantum field theory (cf. [A]),
it becomes very important to study the behavior of natural analytic invariants un-
der the splitting of manifolds. The first splitting formula, for the most fundamen-
tal invariants--the index of Dirac operators, was proved by Atiyah-Patodi-Singer
