Title: Fluctuation theory for completely asymmetric Markov processes
Abstract: We study the class of completely asymmetric standard processes living on an interval of the real line, that is for strong Markov processes having jumps only in one direction. This class of processes, which are a natural generalization of one dimensional-diffusions, arises naturally in risk theory. It also encompasses many interesting instances such as branching processes with immigration, spectrally negative Lévy processes… Under mild conditions, we present two original methodologies for characterizing the Laplace transform of their first exit times from an interval. We also discuss several potential theoretic properties and provide an expression of their resolvent densities. Finally, we illustrate our techniques by easily recovering the well-known fluctuation identities of spectrally negative Lévy processes. The talk is based on joint work with Vincent Vigon (IRMA, Strasbourg, France)
