A Note on $g$-Angle between Two Subspaces in a Normed Space

Functional Analysis 2019-02-26 v2

Abstract

We introduce a new 22-norm on a normed space using a semi-inner product gg on the space. Using the 22-norm, we propose a formula for the gg-angle between 22-dimensional subspaces in the space. Our formula serves as a revision of the one proposed by Nur {\it et al.} \cite{Nur1}.
