A new sampling density condition for shift-invariant spaces

A. Antony Selvan

Let $X = {x_{i} : i \in Z}$ , $\dots < x_{i - 1} < x_{i} < x_{i + 1} < \dots$ , be a sampling set which is separated by a constant $γ > 0$ . Under certain conditions on $ϕ$ , it is proved that if t…

Separation of zeros and a Hermite interpolation based frame algorithm for band limited functions

A. Antony Selvan, R. Radha

It is shown that if a non-zero function $f \in B_{σ}$ has infinitely many double zeros on the real axis, then there exists at least one pair of consecutive zeros whose distance apart…
