一个{\em sectional-Anosov flow}是一个向量场在一个紧致流形上向内横向于边界,使得最大不变集是截面双曲的(在\cite{mm}的意义下)。我们证明了任意C^2 $传递的截面Anosov流都有唯一的SRB测度,并且在小的随机扰动下是随机稳定的。
A {\em sectional-Anosov flow} is a vector field on a compact manifold inwardly transverse to the boundary such that the maximal invariant set is sectional-hyperbolic (in the sense of \cite{mm}). We prove that any $C^2$ transitive sectional-Anosov flow has a unique SRB measure which is stochastically stable under small random perturbations.
