The spectral flow is a well‐known quantity in spectral theory that measures the variation of spectra about 0 along paths of selfadjoint Fredholm operators. The aim of this work is twofold. Firstly,

We consider a curve of Fredholm pairs of Lagrangian subspaces in a xed Banach space with continuously varying weak symplectic structures. Assuming vanishing index, we obtain intrin- sically a

Abstract. Let $A(t)$ be a path of bounded operators on a real Hilbert space, hyperbolic at $\pm \infty$. We study the Fredholm theory of the operator $F_A=d/dt-A(t)$. We relate the Fredholm property
The uniqueness of the spectral flow on spaces of unbounded self--adjoint Fredholm operators
We discuss several natural metrics on spaces of unbounded self--adjoint operators and their relations, among them the Riesz and the graph metric. We show that the topologies of the spaces of Fredholm

We generalise the well known index bundle construction of Atiyah and Janich to families of (generally unbounded) Fredholm operators which are assumed to be continuous with respect to the gap
