Analytic Deformations of the Spectrum of a Family of Dirac Operators on an Odd-Dimensional Manifold with Boundary
Share this pageP. Kirk; E. Klassen
The subject of this memoir is the spectrum of a
Dirac-type operator on an odd-dimensional manifold M with boundary
and, particularly, how this spectrum varies under an analytic
perturbation of the operator. Two types of eigenfunctions are
considered: first, those satisfying the “global boundary
conditions” of Atiyah, Patodi, and Singer and second, those which
extend to \(L^2\) eigenfunctions on M with an infinite collar
attached to its boundary.
The unifying idea behind the analysis of these two types of
spectra is the notion of certain “eigenvalue-Lagrangians” in
the symplectic space \(L^2(\partial M)\), an idea due to Mrowka
and Nicolaescu. By studying the dynamics of these Lagrangians, the
authors are able to establish that those portions of the two types of
spectra which pass through zero behave in essentially the same way (to
first non-vanishing order). In certain cases, this leads to
topological algorithms for computing spectral flow.
