REMARKS ON PASICKI'S ABSTRACT METRIC SPACES AND LIFSHITS'S CONSTANT.
- Authors
KIRK, WILLIAM A.; SHAHZAD, NASEER
- Abstract
In attempting to formulate a more axiomatic approach to metric fixed point theory, some recent concepts due to Lech Pasicki give rise to a number of intriguing problems, especially regarding the Lifshits constant of such spaces. We review these results here, with an emphasis on a number of questions that seem to remain open. For the convenience of the reader certain proofs of known results are also included. Some new observations are also included.
