摘要
In this papier, a homotopy index (Conley index) which can be applied to non-autonomous differential equations is defined. It is proved that the index is well defined, and several theorems concerning its basic properties are established. The second part of this paper is concerned with the application of this index to (non-autonomous) ordinary differential equations as well as (non-autonomous) semilinear parabolic equations. Finally, several existence results for bounded solutions of asymptotically linear non-autonomous equations are proved. We also consider the existence of recurrent or Poisson stable solutions.
