Multiplicity theorem of singular Spectrum for general Anderson type Hamiltonian

Anish Mallick, Dhriti Ranjan Dolai

In this work, we focus on the multiplicity of singular spectrum for operators of the form $A^{\omega }=A+{\sum }_n{\omega }_n{C}_n$ on a separable Hilbert space $\mathcal{H}$, for a self-adjoint ope…
