review text: The author studies a variation of best \(L_ P\) approximation via a new ``norm''. He deals with problems of existence and uniqueness and proves several theorems analogous to questions pertaining to the theory of best uniform approximation such as: Characterization, de la Vallée Pousin's bound and strong uniqueness.
