In mathematics, more specifically in functional analysis, a subset of a topological vector space is said to be a total subset of if the linear span of is a dense subset of [1] This condition arises frequently in many theorems of functional analysis.

Examples

edit

Unbounded self-adjoint operators on Hilbert spaces are defined on total subsets.
