Abstract
Let be continuous mappings of a compactum onto compacta , . The following theorem is known for : if any bounded function on can be represented in the form , where and are bounded functions on and , then any continuous can be represented in the same form with continuous and . An example is constructed showing that the analogous theorem is false for .
