Abstract

H-sets and minimal conditions can be used as criteria for best uniform approximations. In this paper both concepts are compared and examples are given that show where these criteria are applicable and where not. For the minimal conditions the dependence of the extremal values on the parameters is investigated and a simple extension of the conditions is pointed out.
