摘要
研究了一类随机时变森林发展系统.通常情况下,随机时变森林系统很难求出解析解.根据Euler方法,构造了系统的数值解,并应用It公式和Burkholder-Davis-Gundy不等式证明了数值解的收敛性.
In this paper,a class of stochastic age-dependent forest evolution system is studied, for which the analytic solutions are difficult to obtain generally. It is proved that numerical approximation solutions based on the Euler scheme will converge to the true solution by using It6 formula and Burkholder-Davis- Gundy inequality.
