摘要翻译:
在Gompertz肿瘤生长模型中,通过考虑癌细胞密度从安全或良性区域内的平均退出时间和逃逸概率,量化了非高斯α-稳定噪声对肿瘤生长模型的影响。将平均退出时间和逃逸概率问题表述为带有分数阶拉普拉斯算子的微分-积分方程。通过数值模拟,研究了当αα变化时,平均退出时间和逃逸概率如何变化或发生分叉。观察到一些分叉现象,并讨论了它们的影响。

英文摘要:
Effects of non-Gaussian $\alpha-$stable L\'evy noise on the Gompertz tumor growth model are quantified by considering the mean exit time and escape probability of the cancer cell density from inside a safe or benign domain. The mean exit time and escape probability problems are formulated in a differential-integral equation with a fractional Laplacian operator. Numerical simulations are conducted to evaluate how the mean exit time and escape probability vary or bifurcates when $\alpha$ changes. Some bifurcation phenomena are observed and their impacts are discussed.
