Weak convergence of summation processes in Besov spaces

Bruno Morel (2004)

Studia Mathematica

Similarity:

We prove invariance principles for partial sum processes in Besov spaces. This functional framework allows us to give a unified treatment of the step process and the smoothed process in the same parametric scale of function spaces. Our functional central limit theorems in Besov spaces hold for i.i.d. sequences and also for a large class of weakly dependent sequences.

Small deviations of iterated processes in the space of trajectories

Andrei Frolov (2013)

Open Mathematics

Similarity:

We derive logarithmic asymptotics of probabilities of small deviations for iterated processes in the space of trajectories. We find conditions under which these asymptotics coincide with those of processes generating iterated processes. When these conditions fail the asymptotics are quite different.

Asymptotic properties of power variations of Lévy processes

Jean Jacod (2007)

ESAIM: Probability and Statistics

Similarity:

We determine the asymptotic behavior of the realized power variations, and more generally of sums of a given function  evaluated at the increments of a Lévy process between the successive times Δ for = 0,1,...,. One can elucidate completely the first order behavior, that is the convergence in probability of such sums, possibly after normalization and/or centering: it turns out that there is a rather wide variety of possible behaviors, depending on the structure of jumps and on the...
