Abstract

In this paper, we present a concept of convergence of sequence, especially, of 2- dimensional subspaces of normed spaces. The properties of the concept are established. As consequences of our definition in an inner product space, we also obtain the continuity property of the angle between two 2-dimensional subspaces of inner product spaces. © 2019 Austral Internet Publishing.
