随机完备性与体积增长

Stochastic completeness and volume growth

Christian Baer, G. Pacelli Bessa

摘要:

1999年有人提出测地线完备黎曼流形的一个体积增长条件可能意味着该流形是随机完备的。这是出于一个大类的例子和一个已知的类似的布朗运动复发的标准。我们表明,建议的含义是不正确的一般。我们也给出了反例的逆蕴涵。

英文摘要:

It has been suggested in 1999 that a certain volume growth condition for geodesically complete Riemannian manifolds might imply that the manifold is stochastically complete. This is motivated by a large class of examples and by a known analogous criterion for recurrence of Brownian motion. We show that the suggested implication is not true in general. We also give counter-examples to a converse implication.
