| Abstract: | The application of the best approximation theory in engineeringneeds to solve the realization of element of the best approximation. This paperdiscusses the character of element of the best polynomial approximation in Or-licz space, gives a necessary and sufficient condition and test criterion for ele-ment of the best polynomial approximation, so the paper may find one path forthe realization of element of the best approximation in Orlicz space. |
