Abstract

In this paper, the concept of Bessel sequence and frame are introduced in semi-inner product spaces. Some properties of the Bessel sequences and frame are investigated in smooth uniformly convex Banach spaces. One characterization of the space of all Bessel sequences has been pointed out. Examples of frames are constructed in the real sequence spaces \(l^{p}\), \(1<p<\infty \).

Keywords

Semi-inner product space Uniformly convex smooth Banach space Bessel sequence Frame
