A formula for the g-angle between two subspaces of a normed space

摘要

AbstractWe develop the notion ofg-angle between two subspaces of a normed space. In particular, we discuss theg-angle between a 1-dimensional subspace and at-dimensional subspace for$$tge 1$$t≥1and theg-angle between a 2-dimensional subspace and at-dimensional subspace for$$tge 2$$t≥2. Moreover, we present an explicit formula for theg-angle between two subspaces of$$ell ^{p}$$?pspaces.]]>
