Optimal Control with Absolutely Continuous Strategies for Spectrally Negative Lévy Processes [PDF]
In the last few years there has been renewed interest in the classical control problem of de Finetti (1957) for the case where the underlying source of randomness is a spectrally negative Lévy process.

Power identities for Lévy risk models under taxation and capital injections
In this paper we study a spectrally negative Lévy process which is refracted at its running maximum and at the same time reflected from below at a certain level. Such a process can for instance be used to model an insurance surplus process subject to tax

Ray Knight theorems for spectrally negative Lévy processes [PDF]
In this paper, we study the law of the local time processes $(L_T^x(X),x\in \mathbb{R})$ associated to a spectrally negative L\'evy process $X$, in the cases $T=\tau_a^+$, the first passage time of $X$ above $a>0$ and $T=\tau(c)$, the first time it ...

Asymptotic behavior of local times of compound Poisson processes with drift in the infinite variance case [PDF]
Consider compound Poisson processes with negative drift and no negative jumps, which converge to some spectrally positive L\'evy process with non-zero L\'evy measure.

On the last exit times for spectrally negative Lévy processes [PDF]
Using a new approach, for spectrally negative Lévy processes we find joint Laplace transforms involving the last exit time (from a semiinfinite interval), the value of the process at the last exit time, and the associated occupation time, which ...

Building Molecules by a Self‐Replicator That Catalyzes Acyl Hydrazone Formation
A self‐replicator efficiently catalyzes the formation of acyl hydrazone bonds between a set of different substrates. In addition to previously reported (bond‐breaking) catalytic activity, this renders the self‐replicator highly promiscuous, which is a good starting point for Darwinian experiments en route to de‐novo life.

The hitting time of zero for a stable process [PDF]
For any two-sided jumping $\alpha$-stable process, where $1 < \alpha < 2$, we find an explicit identity for the law of the first hitting time of the origin. This complements existing work in the symmetric case and the spectrally one-sided case; cf.

Exact joint laws associated with spectrally negative Lévy processes and applications to insurance risk theory [PDF]
We consider the spectrally negative Lévy processes and determine the joint laws for the quantities such as the first and last passage times over a fixed level, the overshoots and undershoots at first passage, the minimum, the maximum, and the duration of

A first passage time problem for spectrally positive Lévy processes and its application to a dynamic priority queue [PDF]
We study a first passage time problem for a class of spectrally positive Lévy processes. By considering the special case where the Lévy process is a compound Poisson process with negative drift, we obtain the Laplace–Stieltjes transform of the steady ...

Optimality of doubly reflected Lévy processes in singular control [PDF]
We consider a class of two-sided singular control problems. A controller either increases or decreases a given spectrally negative Lévy process so as to minimize the total costs comprising of the running and controlling costs where the latter is ...
