On existence of solutions to backward stochastic differential equation with generalized left-Lipschitz coefficients
-
摘要: 证明了一类生成元满足广义左Lipschitz条件的倒向随机微分方程解的存在性.通过单调迭代方法构造了一列单调的解序列, 然后证明其极限存在,并为原方程的解.并值得一提的是,这里的生成元g既可以关于变量y不连续,同时g关于变量y和z的变换范围也可以与时间参数t有关.

Abstract: In this paper, we proved the existence of the solution to a backward stochastic differential equations (BSDE) with the generator satisfying the generalized left-Lipschitz condition. The key idea for dealing with the problem consists in constructing a monotonic sequence of solutions to BSDE and then passing to thelimit. We construct a monotonic sequence of solutions by monotonic iteration technique. It is worth noting that the generator may be not continuous with respect to variable yand the varying of generator with respect to variables y and z may be not uniformly with respect to time parameter t.-
