摘    要:本文建立了A-映象的不动点指数理论,它类似于A-proper 映象的不动点指数理论;前者不要求空间具有完备投影逼近格式,而后者需要.然后应用这种理论获得了 A-映象的一些非零不动点定理,它们包含了范数形式的拉伸与压缩不动点定理.由于某些全连续映象是 A-映象,因此我们的结果改进了关于全连续映象的某些重要定理.

关 键 词:A-映象  楔形  不动点指数  非零不动点定理

Abstract:The degree of A-maps from a normed space to another one was developed by Kryszewski in 1989,and its appli-cations could be found in Kryszewski's paper of 1990. Here we develope a fixed point index of A-maps from a normed space to itself.Using the index theory,we obtain some new nonzero fixed point theorems,which can not be proved by using the degree obtained in the Kryszewski's papers mentioned above.
Keywords:A-map  wedge  fixed point index  nonzero fixed point theorem
