关于不动点研究中的拓扑度方法
THE METHOD OF TOPOLOGICAL DEGREE IN THE STUDY OF FIXED POINT
【摘要】 本文用拓扑度方法放宽了Petryshyn不动点定理边界条件,研究了某类代数方程组可解性等问题。
【Abstract】 The method of topological degree has been introduced to broaden the boun- dary conditions in Potryshyn fixed point theorems and so study the solvabi - lity of some types of algebraic equations.
