Scattering Theory and Adiabatic Decomposition of the $\z$-determinant of the Dirac Laplacian

In this note we announce the adiabatic decomposition formula for the $\z$-determinant of the Dirac Laplacian. Theorem \ref{t:apssplit} of this paper extends the result of our earlier work (see \cite{JPKW1} and \cite{JPKW2}), which covered the case of the invertible tangential operator. The presence of the non-trivial kernel of the tangential operator requires careful analysis of the small eigenvalues of the Dirac Laplacian, which employs elements of scattering theory.
