$L_{2}$-variation of Lévy driven BSDEs with non-smooth terminal conditions

Abstract: We consider the L 2 -regularity of solutions to backward stochastic differential equations (BSDEs) with Lipschitz generators driven by a Brownian motion and a Poisson random measure associated with a Lévy process (X t ) t∈ [0,T ] . The terminal condition may be a Borel function of finitely many increments of the Lévy process which is not necessarily Lipschitz but only satisfies a fractional smoothness condition. The results are obtained by investigating how the special structure appearing in the chaos expansi… Show more

“…As to BSDEs driven by other discontinuous random sources, Xia [72] and Bandini [6] studied BSDEs driven by a random measure; Confortola et al [25,26] considered BSDEs driven by a marked point process; [61,5,66,36] analyzed BSDEs driven by Lévy processes; [2,68,46] discussed BSDEs driven by a process with a finite number of marked jumps.…”

“…In case of BSDEs driven by a Poisson random measure, Bouchard and Elie [3] have proposed a scheme based on the dynamic programming equation and studied the rate of convergence of the method when the terminal condition is given by ξ = g(X T ), where g is a Lipschitz function and X is a forward process. More recently, Geiss and Steinicke [9] have extended this result to the case of a terminal condition which may be a Borel function of finitely many increments of the Lévy forward process X which is not necessarily Lipschitz but only satisfies a fractional smoothness condition. In the case of jumps driven by a compensated Poisson process, Lejay, Mordecki and Torres [15] have developed a fully implementable scheme based on a random binomial tree, following the approach proposed by Briand, Delyon and Mémin [5].…”

“…The L p -variation of the solution of certain BSDEs depends on the Malliavin fractional smoothness of the terminal condition f (Y 1 ). This was shown with more general terminal conditions for the Brownian motion by C. Geiss, S. Geiss and Gobet [9] and S. Geiss and Ylinen [16] and for p = 2 for general L 2 -Lévy processes by C. Geiss and Steinicke [12].…”
