Abstract
Recently, Takahashi has introduced the James and von Neumann-Jordan type constants. In this
paper, we present some suffcient conditions for uniform normal structure and therefore the fixed
point property of a Banach space in terms of the James and von Neumann-Jordan type constants
and the Ptolemy constant. Our main results of the paper signicantly generalize and improve many
known results in the recent literature.
