Abstract

In this paper, we introduce the idea of constructing sequence spaces with elements in an n-norm space in comparison with the spaces c0, c, and the Orlicz space Mand extend the notion of n-norm to such spaces. Further we state and define some statements about the n-best approximation in n-normed spaces.
