On the calibration of survival models with competing risks
Julie Alberge, Tristan Haugomat, Gaël Varoquaux +1
Survival analysis deals with modeling the time until an event occurs, and accurate probability estimates are crucial for decision-making, particularly in the competing-risks settin…
Lévy-type processes: convergence and discrete schemes
Mihai Gradinaru, Tristan Haugomat
We characterise the convergence of a certain class of discrete time Markov processes toward locally Feller processes in terms of convergence of associated operators. The theory of…
Local Skorokhod topology on the space of cadlag processes
Mihai Gradinaru, Tristan Haugomat
We modify the global Skorokhod topology, on the space of cadlag paths, by localising with respect to space variable, in order to include the eventual explosions. The tightness of f…
Locally Feller processes and martingale local problems
Mihai Gradinaru, Tristan Haugomat
This paper is devoted to the study of a certain type of martingale problems associated to general operators corresponding to processes which have finite lifetime. We analyse severa…
On the a.c. spectrum of 1D discrete Dirac operator
Sylvain Golenia, Tristan Haugomat
In this paper, under some integrability condition, we prove that an electrical perturbation of the discrete Dirac operator has purely absolutely continuous spectrum for the one dim…
