Abstract:
Stability of the family of integer translations of exponential spline $U_{m,p}$ for arbitrary $m,p$ is proven; Riesz bounds are determined. The method presented in the paper allows to calculate Riesz bounds for the convolution of a B-spline of an arbitrary order and a function with an appropriated Fourier transform.
Keywords:
E-spline, Riesz basis, Riesz bounds, functional series.
