Über die Stetigkeit einer Funktion von zwei Veränderlichen unter Monotonie-Bedingungen

Manfred Krtscha , Peter Volkmann

Abstract

Let T, E, F be topological spaces, and let E, F also be preordered with some compatibility between topology and order stucture. Theorem: If f(t,x): T×EF is separately continuous with respect to its variables and monotone non-decreasing with respect to x, then f is continuous. The case of ordered normed spaces E, F is discussed in detail.
