In [[mathematics]], the '''structure theorem for Gaussian measures''' shows that the [[abstract Wiener space]] construction is essentially the only way to obtain a [[Strictly positive measure|strictly positive]] [[Gaussian measure]] on a [[separable space|separable]] [[Banach space]]. It was proved in the 1970s by [[Gopinath Kallianpur|Kallianpur]]&ndash;SatoSatô&ndash;Stefan and [[Richard M. Dudley|Dudley]]&ndash;[[Jacob Feldman|Feldman]]&ndash;[[Lucien le Cam|le Cam]].<!-- I don't see those papers cited here. -->

There is the earlier result due to H. Satô (1969) <ref>[http://projecteuclid.org/DPubS/Repository/1.0/Disseminate?view=body&id=pdf_1&handle=euclid.nmj/1118797795 H. Satô, Gaussian Measure on a Banach Space and Abstract Wiener Measure], 1969.</ref> which proves that "any Gaussian measure on a separable Banach space is an [[abstract Wiener space | abstract Wiener measure]] in the sense of [[Leonard Gross | L. Gross]]". The result by Dudley et al. generalizes this result to the setting of Gaussian measures on a general [[topological vector space]].
