某些地图的有理截面范畴

The rational sectional category of certain maps

J. G. Carrasquel-Vera

摘要:

我们给出了允许同伦收缩的有理映射的截面范畴的一个简单的代数刻画。作为特例,我们得到了有理Lusternik-Schnirelmann范畴的Félix-Halperin定理,并证明了Jessup-Murillo-Parent关于有理拓扑复杂性的猜想.我们还给出了Doeraene-El Haouari意义下的关系范畴的一个刻画。

英文摘要:

We give a simple algebraic characterisation of the sectional category of rational maps admitting a homotopy retraction. As a particular case we get the Félix-Halperin theorem for rational Lusternik-Schnirelmann category and prove the conjecture of Jessup-Murillo-Parent on rational topological complexity. We also give a characterisation for relative category in the sense of Doeraene-El Haouari.
