Jul 31, 2018 at 19:07 comment added Nate Eldredge Classical Wiener measure, on the space of continuous functions, is defined on the Borel $\sigma$-algebra (or its completion). And every continuous function is measurable with respect to the Borel $\sigma$-algebra. This is completely trivial and there really are no details: under a continuous function, the preimage of every open set is open and hence Borel, so the function is measurable.
Jul 31, 2018 at 19:03 comment added Arnold Neumaier @NateEldredge; Where can I find a detailed argument? I mean the sigma algebra with respect to which the Gaussian measure is defined.
Jul 31, 2018 at 16:30 comment added Nate Eldredge If $f$ is continuous then it's certainly measurable, no further assumptions needed, assuming you mean measurable with respect to the Borel $\sigma$-algebra. Did you mean to write something else?
