Function Space

 

a set of functions for which there is defined a notion of distance or, more generally, of proximity between any two functions. A function space is called linear if, along with any two elements f1 and f2 it contains all their linear combinations αf1, + βf2, where α and β are real or complex numbers. An example of a linear function space is the space C(a, b) of all continuous functions on the interval [a, b] with the distance p(f1, f2) between two functions being given by the formula

Function spaces are the most important concrete linear spaces studied in functional analysis. [28–388–1 ]

This volume examines the Gaussian random fields using the structure of the Hilbert space of functions on the parameter space associated with the covariance, or the Reproducing Kernel Hilbert Space (RKHS), with applications of these ideas to research in finance, spatial statistics, and the filtering and analytic problem related to fractional Brownian motion.

Gautam's results [10] make clear that membership in VMO (the space of functions of vanishing mean oscillation) is central to the Balian-Low Theorem.
For a choice of appropriate weights we can identify the space of functions with certain smoothness and decay properties as a modulation space.
