A necessary and sufficient condition with respect to the growth of barrier is also explored to ensure the existence of a solution. And, we show that the solutions may be approximated by the penalization method and by some sequences of solutions of reflected BSDEs. These results are obtained due to the development of those existing ideas and methods together with the application of new ideas and techniques, and they unify and improve some known works.展开更多

We prove the existence and uniqueness of M-solutions of BSVIEs in Lp (1 〈 p 〈 2), which extends the existing results on M-solutions. The unique solvability of adapted solutions of BSVIEs in Lp (p 〉 1) is also considered, which also generalizes the results in the existing literature.展开更多

文摘We prove several existence and uniqueness results for Lp (p 〉 1) solutions of reflected BSDEs with continuous barriers and generators satisfying a one-sided Osgood condition together with a general growth condition in y and a uniform continuity condition or a linear growth condition in z. A necessary and sufficient condition with respect to the growth of barrier is also explored to ensure the existence of a solution. And, we show that the solutions may be approximated by the penalization method and by some sequences of solutions of reflected BSDEs. These results are obtained due to the development of those existing ideas and methods together with the application of new ideas and techniques, and they unify and improve some known works.
