Total set

In functional analysis, a total set (also called a complete set) in a vector space is a set of linear functionals T such that if the inner product (t,s) = 0 for all t in T, then s = 0 is the zero vector.^[1]

In a more general setting, a subset T of a topological vector space V is a total set or fundamental set if the linear span of T is dense in V.^[2]
