New Geometric Constant Related to the P-angle Function in Banach Spaces
Zhijian Yang, Yongjin Li
In this paper, combined with the P-angle function of Banach spaces and the geometric constants that can characterize Hilbert spaces, the new angular geometric constant is defined.…

Inscribed triangles in the unit sphere and a new class of geometric constants
Bingren Chen, Qi Liu, Yongjin Li
We will introduce a new geometric constant GL(X) based on the constant H(X) proposed by Gao. We first further survey the constant H(X) and discuss some of the properties of this co…
