Schoenberg matrices of radial positive definite functions and Riesz sequences in $L^{2} (R^{n})$

L. Golinskii, M. Malamud, L. Oridoroga

Given a function $f$ on the positive half-line $R_{+}$ and a sequence (finite or infinite) of points $X = {x_{k}}_{k = 1}^{ω}$ in $R^{n}$ , we define and study matrices $\kS_X(f)=\|f(|x_i-x…

On the completeness and Riesz basis property of root subspaces of boundary value problems for first order systems and applications

Anton A. Lunyov, Mark M. Malamud

The paper is concerned with the completeness property of root functions of general boundary value problems for $n \times n$ first order systems of ordinary differential equations o…

One-dimensional Schroedinger operators with delta-prime-interactions on Cantor-type sets

Jonathan Eckhardt, Aleksey Kostenko, Mark Malamud +1

We introduce a novel approach for defining a $δ^{'}$ -interaction on a subset of the real line of Lebesgue measure zero which is based on Sturm-Liouville differential expression with m…
