FIBERED BOUNDARIES AND CALORONS.

We use the index formula for fibered boundaries to compute the LL2-index of the Dirac operator twisted by an Anti-Self-Dual instanton defined on X S1, where X is a complete asymptotically conical three-manifold. As a particular case of this calculation, we get another derivation of the index formula for the Dirac operator twisted by a caloron on R3 x S1. [ABSTRACT FROM AUTHOR]
