A Birkhoff-Orthogonal Dehghan--Rooin Type Constant in Banach Spaces

Jia Du, Tingting Hu, Wenwen Zhang +1

For a real Banach space $X$ . The Dehghan--Rooin magnitude compares the angular distance $α [x, y] = ∥ x /∥ x ∥ - y /∥ y ∥∥$ together with the skew angular distance $β[x,y]=\|x/\|y\|-y/\|x…

Skew-Parameterized Geometric Constants in Banach Spaces

Qing Du, Wenwen Zhang, Zhiyao Fang +1

Building on the family of geometric constants introduced by Amini-Harandi and Rahimi, we define a skew-parameterized family on real normed spaces by replacing the classical symmetr…
