关于Volterian二次随机算子的同伦

On homotopy of volterrian quadratic stochastic operators

Farrukh Mukhamedov, Mansoor Saburov

摘要:

本文引入了两个Volterra算子的同伦概念,它与这类算子的不动点有关。建立了两个Volterra算子同伦的判别准则,从而得到了这两个算子对应的竞赛图是相同的。由于\cite{Ga1},这使我们有可能知道同伦Volterra算子的轨迹的一些信息。此外,它表明,任何Volterra q.s.o.给定的面至少有两个对整个单形的同伦扩张。

英文摘要:

In the present paper we introduce a notion of homotopy of two Volterra operators which is related to fixed points of such operators. It is establish a criterion when two Volterra operators are homotopic, as a consequence we obtain that the corresponding tournaments of that operators are the same. This, due to \cite{Ga1}, gives us a possibility to know some information about the trajectory of homotopic Volterra operators. Moreover, it is shown that any Volterra q.s.o. given on a face has at least two homotopic extension to the whole simplex.
