The behavior near the origin of the supremum functional in a process with stationary independent increments
Let {X(t),t ≧0} be a process with stationary independent increments which is stochastically continuous with right-continuous paths and normalized so that X(0)=0. Let Z 1(t) = X(t), Z 2(t) = sup0≦s≦t X(s) and Z 3 (t) = largest positive jump of X in (0, t] if there is one; = 0 otherwise. Then for i = 1,2,3 and x > 0: lim t↓0 t —1 P[Zi (t) > x] = M +(x) at all points of continuity of M +, the Lévy measure of X.
