Dirac operators lie at the heart of both mathematical physics and differential geometry, offering a unifying framework for the treatment of quantum mechanical systems and geometrical invariants. Their ...

Inverse problems in spectral theory address the challenge of reconstructing differential operators from observed spectral data. This field, rich in both theoretical and applied mathematics, underpins ...

In this paper, we introduce operator-valued weighted bi-shifts on the Hilbert space l2(ℕ, 𝓗), of all square-summable sequences whose elements are in a complex Hilbert space 𝓗, and study their ...
