On a stopped Brownian motion formula of H.M.~Taylor (
Brownian motion)
This formula gives the joint distribution of $X_T$ and $T$, where $X$ is standard Brownian motion and $T$ is the first time $M_T-X_T=a$, $M_t$ denoting the supremum of $X$ up to time $t$. Two different new proofs are given
Comment: For the original proof of Taylor see
Ann. Prob. 3, 1975. For modern references, we should ask Yor
