摘要

In this paper we continue the study of the general convex functions, which are introduced in our former paper (Taskovic , Math. Japonica, 37(1992), 367-372). We prove that if D is contained in R~n a convex and open set, and if f : D → R is a general J-inner function for some bounded function g : f(D)~2 → R, then if f is locally bounded at a point of D, then it is continuous in D. In this paper, also, we give the statement, which is directly a consequence of the preceding statement for a measurable function f. Since every convex function (also an additive function) is general J-inner function, we obtain as a particular case of the preceding statements the results of Steinhaus, Banach, Frechet, Sierpinski, Kuczma and some others.
