We present a general setting where wavelet filters and multiresolution decompositions can be defined, beyond the classical $L^{2} (R, d x)$ setting. This is done in a fr…

A new realization of rational functions, with applications to linear combination interpolation

Daniel Alpay, Palle Jorgensen, Izchak Lewkowicz +1

We introduce the following linear combination interpolation problem (LCI): Given $N$ distinct numbers $w_{1}, \dots w_{N}$ and $N + 1$ complex numbers $a_{1}, \dots, a_{N}$ and $c$ , find all…
