Let Xt be any additive process in R d. There are finite indices δi, βi, i = 1, 2 and a function u, all of which are defined in terms of the characteristics of Xt, such that lim inf t→0 u(t) −1/η X * t = 0, if η > δ1, ∞, if η < δ2, lim sup t→0 u(t) −1/η X * t = 0, if η > β2, ∞, if η < β1, a.s., where X * t = sup 0≤s≤t |Xs|. When Xt is a Lévy process with X0 = 0, δ1 = δ2, β1 = β2 and u(t) = t. Th...
