非自治Conley指标理论:连接同态

Nonautonomous Conley Index Theory: The Connecting Homomorphism

Axel Jänig

摘要:

孤立不变集的吸引-排斥分解产生所谓的连接同态。这些同态揭示了底层动力系统的连接轨迹的存在和结构的信息。为了给一个有意义的一般原则,非自治问题,非自治的同源康利指数表示为一个直接的限制。此外,它表明,一个非平凡的连接同态意味着,在动力系统水平上,一种一致的吸引子-排斥子分解的连通性。

英文摘要:

Attractor-repeller decompositions of isolated invariant sets give rise to so-called connecting homomorphisms. These homomorphisms reveal information on the existence and structure of connecting trajectories of the underlying dynamical system. To give a meaningful generalization of this general principle to nonautonomous problems, the nonautonomous homology Conley index is expressed as a direct limit. Moreover, it is shown that a nontrivial connecting homomorphism implies, on the dynamical systems level, a sort of uniform connectedness of the attractor-repeller decomposition.
