Slowdown for time inhomogeneous branching Brownian motion

Published 8 May 2012 in math.PR | (1205.1769v1)

Abstract: We consider the maximal displacement of one dimensional branching Brownian motion with (macroscopically) time varying profiles. For monotone decreasing variances, we show that the correction from linear displacement is not logarithmic but rather proportional to $T^{1/3}$. We conjecture that this is the worse case correction possible.
