D. Herzog 和 J. Mattingly 证明,具有有限时间爆炸解的 ℂ 值多项式 ODE 可以通过添加 ℂ 值布朗噪声来稳定。在本文中,我们将他们的结果扩展到具有有限时间爆炸解的耦合 ODE 的 ℂ2 值系统。我们通过分析和数值证明,通过添加合适的布朗噪声可以在我们的设置中实现稳定,并且所得的 SDE 系统是遍历的。该证明使用吉尔萨诺夫定理来引入从我们的ℂ2-系统到准ℂ-系统的时间变化,类似于赫尔佐格和马丁利研究的系统。
D. Herzog and J. Mattingly have shown that a ℂ-valued polynomial ODE with finite-time blow-up solutions may be stabilized by the addition of ℂ-valued Brownian noise. In this paper, we extend their results to a ℂ2-valued system of coupled ODEs with finite-time blow-up solutions. We show analytically and numerically that stabilization can be achieved in our setting by adding a suitable Brownian noise, and that the resulting system of SDEs is ergodic. The proof uses the Girsanov theorem to induce a time change from our ℂ2-system to a quasi-ℂ-system similar to the one studied by Herzog and Mattingly.
