We consider Taylor approximations of matrix functions and establish bounds controlling the size of a perturbation in terms of the size of the Taylor remainder or, equivalently, the associated spectral shift function(s). This can be viewed as a stabil

Given a complex, separable Hilbert space $$\mathcal{H}$$ , we consider differential expressions of the type τ = −(d2/dx2) $$I_\mathcal{H}$$ + V(x), with x ∈ (x0,∞) for some x0 ∈ ℝ, or x ∈ ℝ (assuming the limit-point property of τ at

This book provides a detailed treatment of the various facets of modern Sturm–Liouville theory, including such topics as Weyl–Titchmarsh theory, classical, renormalized, and perturbative oscillation theory, boundary data maps, traces and determin

We revisit an archive submission by Denton et al. (Eigenvectors from eigenvalues: a survey of a basic identity in linear algebra. arXiv:1908.03795v3 [math.RA], 2019) on $$n \times n$$ self-adjoint matrices from the point of view of self-adjoint Diric

We make a number of comments on Chebyshev polynomials for general compact subsets of the complex plane. We focus on two aspects: asymptotics of the zeros and explicit Totik--Widom upper bounds on their norms.

We determine which sets saturate the Szegő and Schiefermayr lower bounds on the norms of Chebyshev Polynomials. We also discuss sets that saturate our optimal Totik–Widom upper bound.
