Stability of backward propagation of chaos

Antonis Papapantoleon, Alexandros Saplaouras, Stefanos Theodorakopoulos

The purpose of the present paper is to introduce and establish a notion of stability for the backward propagation of chaos with respect to (initial) data sets. Consider, for exampl…

Mind the jumps: when 2BSDEs meet semi-martingales

Dylan Possamaï, Marco Rodrigues, Alexandros Saplaouras

We construct an aggregated version of the value processes associated with stochastic control problems, where the criterion to optimise is given by solutions to semi-martingale back…

Existence, uniqueness and propagation of chaos for general McKean-Vlasov and mean-field BSDEs

Antonis Papapantoleon, Alexandros Saplaouras, Stefanos Theodorakopoulos

We consider backward stochastic differential equations (BSDEs) with mean-field and McKean-Vlasov interactions in their generators in a general setting, where the drivers are square…

A general and sharp regularity condition for integro-differential equations with non-dominated measures

Alexandros Saplaouras

The aim of this work is to present the regularity condition (also known in the literature as structure condition) an integro-differential operator may satisfy in order for the domi…

Convergence rates for Backward SDEs driven by Lévy processes

Chenguang Liu, Antonis Papapantoleon, Alexandros Saplaouras

We consider Lévy processes that are approximated by compound Poisson processes and, correspondingly, BSDEs driven by Lévy processes that are approximated by BSDEs driven by their…
