Derivative martingale of the branching Brownian motion in dimension d ≥ 1
We consider a branching Brownian motion in R d . We prove that there exists a random subset Θ of S d−1 such that the limit of the derivative martingale exists simultaneously for all directions θ ∈ Θ almost surely. This allows us to define a random measure on S d−1 whose density is given by the deriv...
