P_1紧与凝聚映象的Altman型不动点

Altman-fixed-points for P_1-compact and Condensing Mappings

利用拓扑度理论在LeraySchauder条件下得到了若干P1紧与凝聚映象的Altman型不动点,进一步推广了著名的Altman定理,改进了有关文献的一些结果.

In this paper using topological degree theory we obtain some new Altman fixed point theorems for P 1 compact and condensing mappings,thus the well known Altman's theoem is generalized,and some corresponding results of some papers are improved.
