摘要
In this paper, we define the modulus of n-dimensional U-flatness as the determinant of an (n+1) x (n+1) matrix. The properties of the modulus are investigated and the relationships between this modulus and other geometric parameters of Banach spaces are studied. Some results on fixed point theory for non-expansive mappings and normal structure in Banach spaces are obtained.
