Construction of the nearest nonnegative Hankel matrix for a prescribed eigenpair
Numerical AlgorithmsWe study the problem of determining whether a prescribed eigenpair $(λ,x)$ can be made an exact eigenpair of a nonnegative Hankel matrix through the smallest possible structured perturbation. The task reduces to check the feasibility of a set of linear constraints that encode both the Hankel structure and entrywise nonnegativity.

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.Abstract Background AAPM Report No. 365 recommends that medical physics graduate programs offer courses covering both mathematical and statistical methods (Section 3.1.7) as well as computational methods and medical informatics (Section 3.1.8). While our program seeks to incorporate both of these essential areas into the curriculum, various financial ...

Invertibility properties of matrix wiener‐hopf plus Hankel integral operators
Mathematical Modelling and Analysis, 2008 We consider matrix Wiener‐Hopf plus Hankel operators acting between Lebesgue spaces on the real line with Fourier symbols presenting some even properties (which in particular include unitary matrix‐valued functions), and also with Fourier symbols which ...
