| 概要 | I will survey the recent progress in topology and
dynamics using the techniques of closed 1-forms.
I will describe a Lusternik–Schnirelmann
type theory for closed 1-forms which includes the focusing effect for
flows and the theory of Lyapunov 1-forms. This approach allows to draw
conclusions about properties of flows by studying homotopical and
cohomological
features of manifolds. |
