Radial positive definite functions and Schoenberg matrices with negative eigenvalues

L. Golinskii, M. Malamud, L. Oridoroga

The main object under consideration is a class $Φ_{n} \ Φ_{n + 1}$ of radial positive definite functions on $R^{n}$ which do not admit \emph{radial positive definite continuation…

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…
