On obtaining simple identities for overshoots of spectrally negative L\'evy processes

TL;DR: In this article, an analytic expression for the distribution of overshoot over a fixed level in terms of the infinitesimal generator and the scale function of the process is given. But the identity involves an auxiliary function and the simplicity of the identity depends very much on the choice of this function.

On the well-posedness of solutions with finite energy for nonlocal equations of porous medium type

TL;DR: In this article, the authors studied the equivalence and well-posedness of different notions of solutions with finite energy for nonlocal porous medium type equations of the form $$\partial_tu-A\varphi(u)=0.

Enhanced Poisson sum representation for alpha-stable processes

TL;DR: These representations aim to provide a conditionally Gaussian framework, which will allow parameter estimation using Rao-Blackwellised versions of state of the art Bayesian computational methods such as particle filters and Markov chain Monte Carlo (MCMC).

A Multivariate Functional Limit Theorem in Weak $$M_{1}$$ Topology

TL;DR: In this article, a functional limit theorem for weakly dependent regularly varying sequences of random vectors was proved for the case where the convergence takes place in the space of valued cadlag functions endowed with the so-called weak $$M_1}$$ topology.

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.
