Regular generalized sampling in T-invariant subspaces of a Hilbert space
Antonio G. García, María J. Muñoz-Bouzo, Gerardo Pérez-Villalón
A regular generalized sampling theory in some structured T-invariant subspaces of a Hilbert space H, where T denotes a bounded invertible operator in H, is established in this pape…

Sampling formulas involving differences in shift-invariant subspaces: a unified approach
Antonio G. García, María J. Muñoz-Bouzo
Successive differences on a sequence of data help to discover some smoothness features of this data. This was one of the main reasons for rewriting the classical interpolation form…
