 Even so, it is possible to define Gaussian measures on infinite-dimensional spaces, the main example being the abstract Wiener space construction.A Borel measure "γ" on a separable Banach space "E" is said to be a non-degenerate (centered) Gaussian measure if, for every linear functional "L" ∈ "E"∗ except "L" = 0, the push-forward measure "L"∗("γ") is a non-degenerate (centered) Gaussian measure on R in the sense defined above.For example, classical Wiener measure on the space of continuous paths is a Gaussian measure.
