Abstract:
We study the relations of almost lower semicontinuity, lower semicontinuity and other generalized lower semicontinuity; then we establish a new approximate selection theorem for almost lower semicontinuous multimaps with the generalized Zima type condition in CC-spaces. Our result unify and extend the approximate selection theorems in many published works.
Keywords:Lower semicontinuity (lsc)   Almost lower semicontinuity (alsc)   Quasi lower semicontinuity (qlsc)   Uniformly u-continuous   Zima type   Approximate selection theorems   LC-metric spaces
