function space
set of functions of a given kind from a set X to a set Y; it is called a space because in many applications it is a topological space (including metric spaces), a vector space, or both
Haar space
function space
Lp space
function spaces generalizing finite-dimensional p norm spaces
sequence space
a vector space whose elements are infinite sequences of real or complex numbers
Hardy field
field consisting of germs of real-valued functions at infinity that are closed under differentiation
learnable function class
in statistical learning theory, a set of functions for which an algorithm can be devised to asymptotically minimize the expected risk, uniformly over all probability distributions
reproducing kernel Hilbert space
Hilbert space of functions in which point evaluation is a continuous linear functional
