Kirby Diagram of Polar Flows on Four-Dimensional Manifolds
摘要
Abstract
We solve the topological classification problem for polar flows on closed four-dimensional manifolds whose set of saddle equilibrium states consists only of points having two-dimensional stable and unstable manifolds. It is shown that the Kirby diagram, which is a framed link on a secant sphere to the flow, is a complete topological invariant for such flows.
