Spectral flow and bifurcation for a class of strongly indefinite elliptic systems

Nils Waterstraat

We consider bifurcation of solutions from a given trivial branch for a class of strongly indefinite elliptic systems via the spectral flow. Our main results establish bifurcation i…

On the space of connections having non-trivial twisted harmonic spinors

Francesco Bei, Nils Waterstraat

We consider Dirac operators on odd-dimensional compact spin manifolds which are twisted by a product bundle. We show that the space of connections on the twisting bundle which yiel…
