摘要

In this paper, we establish∏ a general existence theorem of maximal elements of condensing mappings in the product X:= Xα of noncompact l.c.-spaces. As an application, we prove that α∈I a family of Lπα-majorized Qα-condensing mappings Tα: X −→ 2 admit a common maximal element under the mild condition that each {x | Tα(x) ≠ ∅} is compactly open.
