Fast approximation by periodic kernel-based lattice-point interpolation with application in uncertainty quantification

Vesa Kaarnioja, Yoshihito Kazashi, Frances Y. Kuo +2

This paper deals with the kernel-based approximation of a multivariate periodic function by interpolation at the points of an integration lattice -- a setting that, as pointed out…

Bounds on the spectrum of nonsingular triangular $(0, 1)$ -matrices

Vesa Kaarnioja

Let $K_{n}$ be the set of all nonsingular $n \times n$ lower triangular $(0, 1)$ -matrices. Hong and Loewy (2004) introduced the numbers $$ c_n={\rm min}\{λ\mid λ~\text{is an eigenvalue…
