ON THE COMPARISON OF THE MARCINKIEWICZ AND LUXEMBURG NORMS OF THE EXPONENTIAL SPACE.

The exponential space, which is a Banach function space, can be defined with two very differently looking, but equivalent norms. In this paper, we give estimates for the best constants of the ratio of these two norms. Our result answers a question of C. Bennett, and R. Sharpley. [ABSTRACT FROM AUTHOR]
