Classification of Coharmonic and Coinvariant Functions for a Levy Process
The Annals of Probability, 1980 Excursion theory is applied to get identities for continuous time ladder variables. The identities are used to classify coharmonic and coinvariant functions for one dimensional Levy processes.

Artificial Cell Catalysts for Biotransformation: Design Principles and Process Integration
Biotechnology and Bioengineering, EarlyView.ABSTRACT Artificial cell catalysts are emerging as programmable biocatalytic platforms for sustainable molecular conversion. By reconstituting enzymes and functional modules within synthetic compartments, they combine the selectivity of biological catalysis with the design flexibility of synthetic materials.

Intrinsic Ultracontractivity for Levy processes
, 2006 We prove the intrinsic ultracontractivity for the semigroup generated by a large class of symmetric Levy processes such that the Levy measure satisfies some conditions in the neighborhood of 0, killed on exiting a bounded and connected Lipschitz domain.

On the reducibility of affine models with dependent Lévy factors
Modern Stochastics: Theory and ApplicationsThe paper is devoted to the study of the short rate equation of the form \[ \text{d}R(t)=F(R(t))\text{d}t+{\sum \limits_{i=1}^{d}}{G_{i}}(R(t-))\text{d}{Z_{i}}(t),\hspace{1em}R(0)={R_{0}}\ge 0,\hspace{3.33333pt}t\gt 0,\] with deterministic functions

Ruin Time and Severity for a Lévy Subordinator Claim Process: A Simple Approach
Risks, 2013 This paper is concerned with an insurance risk model whose claim process is described by a Lévy subordinator process. Lévy-type risk models have been the object of much research in recent years. Our purpose is to present, in the case of a subordinator, a

Minimizing Banking Risk in a Lévy Process Setting
Journal of Applied Mathematics, 2007 The primary functions of a bank are to obtain funds through deposits from external sources and to use the said funds to issue loans. Moreover, risk management practices related to the withdrawal of these bank deposits have always been of considerable ...
