J an 2 00 6 CGMY and Meixner Subordinators are Absolutely Continuous with respect to One Sided Stable
نویسندگان
چکیده
We describe the CGMY and Meixner processes as time changed Brownian motions. The CGMY uses a time change absolutely continuous with respect to the one-sided stable (Y/2) subordinator while the Meixner time change is absolutely continuous with respect to the one sided stable (1/2) subordinator. The required time changes may be generated by simulating the requisite one-sided stable subordinator and throwing away some of the jumps as described in Rosinski (2001).

If f is a measurable transformation of a Lebesgue measure space (X,A, λ) to itself, that does not preserve the measure λ, one can study the invariant measures of f and compare them to λ. A especially interesting case is when f is non-singular with respect to λ (in the sense thatλ(A) = 0 iff λ( f(A)) = 0), but nevertheless there exist no σ-finite invariant measure which is absolutely continuous ...

We consider billiards with a single cusp where the walls meeting at the vertex of the cusp have zero one-sided curvature, thus forming a flat point at the vertex. For Hölder continuous observables, we show that properly normalized Birkoff sums, with respect to the billiard map, converge in law to a totally skewed α-stable law.
متن کاملMinimal q-entropy martingale measures for exponential time-changed Lévy processes
In this paper, we consider structure preserving measure transforms for time-changed Lévy processes. Within this class of transforms preserving the time-changed Lévy structure, we derive equivalent martingale measures minimizing relative q-entropy. Structure preservation is found to be an inherent property of minimal q-entropy martingale measures under continuous time changes, whereas it imposes...
