Abstract:
In 2005, Garcia, Perez-Villala and Portal gave the regular and irregular sampling formulas in shift invariant space $V_\varphi$ via a linear operator $T$ between $L^2(0, 1)$ and $L^2(R)$. In this paper, in terms of bases for $L^2(0,\,\alpha)$, two sampling theorems for $\alpha{\mathbb{Z}}$-shift invariant spaces with a single generator are obtained.
