基于上同调诱导映射特征值的周期点存在性判据
A criterion for the existence of periodic points based on the eigenvalues of maps induced in cohomology
摘要:
对于有理上同调同构于生成元为奇数维的分次外代数和所有元素为偶数次的分次代数的张量积的空间,基于上同调诱导的映射的特征值给出了周期点存在的一个判据.我们给出了一些自然的例子,这样的空间,并提供一些非平凡的。我们也给一个反例,要求在\cite{duan}有没有证据。
英文摘要:
We present a criterion for the existence of periodic points based on the eigenvalues of maps induced in cohomology for spaces with rational cohomology isomorphic to a tensor product of a graded exterior algebra with generators in odd dimensions and a graded algebra with all elements of even degree. We give a number of natural examples of such spaces and provide some non-trivial ones. We also give a counterexample to a claim in \cite{duan} given there without proof.
