【Abstract】 The purpose of the paper is to study the continuous approximate selection problem. The results presented in this paper show that a set\|valued mapping with almost lower semicontinuity has a continuous approximate selection. By using the result, an almost fixed point theorem is obtained and the Michael continuous approximate selection theorem is improved.更多还原
