摘要
本文先在(π)1空间的闭集上证明了凝聚映射必为A-proper映射,运用此性质证明了型如f(x)-λx=0方程当f为弱内向、半李普希兹映射时是弱逼近可解的,若f为李普希兹型映射,方程还是强逼近可解的.
In this paper, the A-properness of condensing map is obtained. Then, we prove that the equation f（x）-λx=0 is feebly approximation solvable for weakly inward and semiLipschitz maps. At the same time,the strongly approximation solvability of the equation for Lipschitz map is established.
