abstract = "We consider the additive martingale Wt (λ) and the derivative martingale ∂Wt (λ) for one-dimensional supercritical super-Brownian motions with general branching mechanism. In the critical case λ = λ0, we prove that √tWt (λ0) converges in probability to a positive limit, which is a constant multiple of the almost sure limit ∂W∞(λ0) of the derivative martingale ∂Wt (λ0). We also prove that, on the survival event, lim supt→∞ √tWt (λ0)=∞almost surely.",
