局部凸空间中的不动点指数和不动点定理

Fixed Point Index and Fixed Point Theorems in Local Convex Space

本广对拟完备Hausdorff局部凸空间中1-Φ-压缩映象定义了不动点指数的概念,据此得到半闭1Φ-压缩映象的某些不动点定理。

In this paper we give the concept of fixed point index of l-Φ-contractive mappings in guasicomplete Hausdorff local convex space.Then we obtain some fixed point theorems of semi-closed 1-Φ-contractive mapping.
