A new upper bound of geometric constant D ( X ) $D(X)$

A new upper bound of geometric constant D ( X ) $D(X)$

Abstract A new constant WD ( X ) $\mathit{WD}(X)$ is introduced into any real 2 n $2^{n}$ -dimensional symmetric normed space X. By virtue of this constant, an upper bound of the geometric constant D ( X ) $D(X)$ , which is used to measure the difference between Birkhoff orthogonality and isosceles...
