摘要
我们考虑由 Cugliandolo 等人 [22] 引入的一类随机自治常微分方程系统,该系统作为球面 p-spin 模型梯度流的非松弛类比。该模型中平衡点期望数量的渐近性近期由 Fyodorov [32] 在高维极限下算出,随后 Garcia [38] 对稳定平衡点期望数量作了类似计算。我们证明对于 ,平衡点数量以及稳定平衡点数量均围绕各自平均值集中,推广了 Subag 与 Zeitouni [61, 64] 在松弛情形下的近期结果。特别地,我们确认该模型经历了从相对不稳定性到绝对不稳定性的转变,此意义由 Ben Arous、Fyodorov 与 Khoruzhenko [11] 给出。
