Abstract:
The paper is devoted to generalization of some classical results about the Banach–Mazur distance to the modified Banach–Mazur distance. The existense of a space uniformly distant in the modified Banach–Mazur distance from all spaces with small basis constant and a space distant in the modified metric from all spaces admitting complex structure is proved. The existense of a real space admitting two complex structures distant in the sense of the complex modified distance is established. The existense of a space having big generalized volume ratio with all of its subspaces of proportional dimension is shown.
