WebOct 26, 2015 · Two reasons: if X is a metric space (as a Banach space is) and X is separable (i.e. has a countable dense subset), then every subset of X also has a countable dense subset. This holds because having a countable dense subset and having a countable base (for the topology) are equivalent in metric spaces. WebThus, in this chapter, we will look at Wiener measure from a strictly Gaussian point of view. More generally, we will be dealing here with measures on a real Banach space E that are centered Gaussian in the sense that, for each x* in the dual space E *, x ∈ E ↦ 〈 x, x *〉, ∈ ℝ is a centered Gaussian random variable.
