Abstract

К. Begl formulates the definitions of continuity and directional derivative in the space Rn in such a way that they respectively have a unified general form for all n and coincide at n=1 with the corresponding definitions for functions of one variable. In addition to the concept of continuity, the concepts of derivative, integral, convergence, semicontinuity, and limit, expressed in a unified and general form, are introduced successively.
