gptkbp:instanceOf gptkb:mathematical_concept
gptkbp:appliesTo gptkb:Hilbert_space
gptkbp:category gptkb:basis_(mathematics)
gptkbp:defines A sequence (x_n) in a Banach space X such that every element x in X can be written uniquely as a convergent series x = sum a_n x_n.
gptkbp:distinctFrom Hamel basis uses finite linear combinations, Schauder basis uses infinite series
gptkbp:example The sequence of unit vectors in l^p spaces (1 ≤ p < ∞) forms a Schauder basis
gptkbp:field functional analysis
gptkbp:generalizes orthonormal basis in Hilbert spaces
