The time at which a L\'evy process creeps

TL;DR: In this paper, it was shown that the renewal function of the bivariate ascending ladder process (L^{-1},H) is continuous on $[0,\infty) and left differentiable on $ [0, \infty] and that the left derivative at $u$ is proportional to the (improper) distribution function of time at which the process creeps over level $u$, where the constant of proportionality is the reciprocal of the (positive) drift of $H$.

On the infinite divisibility of inverse Beta distributions

TL;DR: In this paper, it was shown that all negative powers of the Gamma distribution are generalized Gamma convolutions, answering a recent question of L. Bondesson, who showed that negative powers are not always a generalized gamma convolution.

The analog formulation of sparsity implies infinite divisibility and rules out Bernoulli-Gaussian priors

TL;DR: This work considers the stochastic processes that can be whitened by linear transformations and shows that the distribution of their samples is necessarily infinitely divisible, which rules out the Bernoulli-Gaussian distribution.

Fractional Fokker-Planck-Kolmogorov equations associated with SDES on a bounded domain

TL;DR: In this article, a fractional generalization of the Fokker-Planck equation associated with a nonlinear stochastic differential equation on a bounded domain is derived and the existence of a unique solution of the corresponding initial-boundary value problems is proved.

The exit problem from the neighborhood of a global attractor for heavy-tailed Lévy diffusions

TL;DR: In this article, the authors considered a deterministic dynamical system with a global attractor A and a unique ergodic measure P concentrated on it, which is uniformly parametrized by the mean of the trajectories in a bounded set D containing A.

Optimal stopping and perpetual options for Lévy processes

TL;DR: A closed formula for prices of perpetual American call options in terms of the overall supremum of the Lévy process, and a corresponding closed formulas for perpetual American put options involving the infimum of the after-mentioned process are obtained.
