具局部Lipschitz非线性项的耗散倒向随机微分方程

Dissipative backward stochastic differential equations with locally Lipschitz nonlinearity

Fulvia Confortola

摘要:

本文研究了无穷维希尔伯特空间H中区间[0,T]上的一类倒向随机微分方程dY(t)= -AY(t)dt-f_0(t,Y(t))dt-f_1(t,Y(t),Z(t))dt + Z(t)dW(t),在时间T上具有给定的最终条件.无界算子A是扇形的和耗散的,非线性函数f_0(t,y)是耗散的,并且定义为y只取H的一个子空间中的值.一个典型的例子是所谓的多项式非线性。应用于随机偏微分方程和自旋系统。

英文摘要:

In this paper we study a class of backward stochastic differential equations (BSDEs) of the form dY(t)= -AY(t)dt -f_0(t,Y(t))dt -f_1(t,Y(t),Z(t))dt + Z(t)dW(t) on the interval [0,T], with given final condition at time T, in an infinite dimensional Hilbert space H. The unbounded operator A is sectorial and dissipative and the nonlinearity f_0(t,y) is dissipative and defined for y only taking values in a subspace of H. A typical example is provided by the so-called polynomial nonlinearities. Applications are given to stochastic partial differential equations and spin systems.
