We provide a comprehensive analysis of matrix–valued Herglotz functions and illustrate
their applications in the spectral theory of self–adjoint Hamiltonian systems including matrix …

This paper presents a review of both classical and modern results pertaining to partial
inverse spectral problems for differential operators. Such problems consist in the recovery of …

We continue the study of the A-amplitude associated to a half-line Schrodinger operator,-
d2/dx2+ q in L2 ((0, b)), b≤∞. A is related to the Weyl-Titchmarsh m-function via m (-κ2)=-κ …

We explicitly determine the high-energy asymptotics for Weyl–Titchmarsh matrices
associated with general Dirac-type operators on half-lines and on $\mathbb {R} $. We also …

The spectral properties of Dirac operators on $(0, 1) $ with potentials that belong entrywise
to $ L_p (0, 1) $, for some $ p\in [1,\infty) $, are studied. The algorithm of reconstruction of the …
