Two results on Gaussian measures.
Abstract:
1. I'll show that Hunt's hypothesis (H) fails for Leonard Gross' infinite dimensional Brownian motion, by exhibiting a subset of the state space of the motion that is hit exactly once for certain starting points. 2. It is well known that a Lebesgue measurable additive function from R to R is necessarily continuous (and linear). I'll show how D. Stroock's recent proof of L. Schwartz's ``Borel graph theorem" can be adapted to show that a ``universally Gaussian measurable" and additive map from one Banach space to another is automatically continuous (and linear).
