We introduce a new 2-norm on a normed space using a semi-inner product g on the space. Using this 2-norm, we propose a formula for the g-angle between 2-dimensional subspaces in the space. Our formula serves as a revision of the one proposed by Nur et al. (Beitr. Algebra Geom. 59(1):133–143, 2018).

关于赋范空间的子空间之间的g角的注记

我们在范空间上使用半内积g引入一个新的2范数。使用该2范数,我们为空间中2维子空间之间的g角提出了一个公式。我们的公式是对Nur等人提出的公式的修正。(Beitr。Algebra Geom。59(1):133–143,2018)。
