Spectral Theory of Families of Self-Adjoint Operators

1 Oct 2014 ... For each n ∈ N, we get families of selfadjoint operators indexed by: (i) the unitary matrix group U(n), and by (ii) a prescribed set of n non- ...

Approximations of strongly continuous families … The problem of approximating the discrete spectra of families of self-adjoint operators that are merely strongly continuous is addressed. It is well-known that the spectrum need not vary continuously (as a set) under strong perturbations. However, it is shown that under an additional compactness assumption the spectrum does vary continuously, and a family of symmetric finite-dimensional

An alternative formulation of the spectral theorem says that every bounded self-adjoint operator is unitarily equivalent to a multiplication operator. The significance of this result is that multiplication operators are in many ways easy to understand. Theorem. … Spectral theory of self-adjoint operators, and …
