Distributional identities for a Lévy process Xt , its quadratic variation process Vt and its maximal jump processes,
are derived, and used to make “small time” (as t ↓ 0) asymptotic comparisons between them. The
representations are constructed using properties of the underlying Poisson point process of the jumps of X.
Apart from providing insight into the connections between X, V , and their maximal jump processes, they
enable investigation of a great variety of limiting behaviours. As an...[Show more]
