Altman不动点定理的一般化

Vague Generalization of the Altman Fixed Point Theorem

利用同伦不变性把不动点定理的条件‖F(x)-x‖2≥‖F(x)‖2-‖x‖2进行了推广,给出了Altman定理在凝聚映射及更二般映射下几个方面的推广形式.

The conditions 1｜｜F（x）-x1｜｜^2≥｜｜F（x）｜｜^2-｜｜x｜｜^2 of the fixed point theorem were extended by usi the homotopic in variance, the generalized forms of the Altman theorem were given in the condensed mapping a mapping of the more general aspects.
