In mathematics, a rigged Hilbert space (Gelfand triple, nested Hilbert space, equipped Hilbert space) is a construction designed to link the distribution and square-integrable aspects of functional analysis. Such spaces were introduced to study spectral theory in the broad sense.{{ safesubst:#invoke:Unsubst||$N=Vague |date=__DATE__ |$B= {{#invoke:Category handler|main}}[vague] }} They bring together the 'bound state' (eigenvector) and 'continuous spectrum', in one place.
