本文证明了具有有界Nash熵的定常梯度Ricci孤子的体积增长估计。我们证明了这种稳定的梯度Ricci孤子的体积增长率不小于这个结果,这一结果不仅改进了(Chan et al.,arxiv:2107.01419,2021年,定理1.3)中的估计,而且是最优的,因为Bryant孤子和Appleton的孤子(Appleton,arxiv:1708.00161,2017年)都有这个增长率。
In this paper, we prove a volume growth estimate for steady gradient Ricci solitons with bounded Nash entropy. We show that such a steady gradient Ricci soliton has volume growth rate no smaller thanThis result not only improves the estimate in (Chan et al., arXiv:2107.01419, 2021, Theorem 1.3), but also is optimal since the Bryant soliton and Appleton’s solitons (Appleton, arXiv:1708.00161, 2017) have exactly this growth rate.
