内容説明・目次
内容説明
The tame flows are ""nice"" flows on ""nice"" spaces. The nice (tame) sets are the pfaffian sets introduced by Khovanski, and a flow \Phi: \mathbb{R}\times X\rightarrow X on pfaffian set X is tame if the graph of \Phi is a pfaffian subset of \mathbb{R}\times X\times X. Any compact tame set admits plenty tame flows. The author proves that the flow determined by the gradient of a generic real analytic function with respect to a generic real analytic metric is tame.
