讲座摘要:

Fixed point theory is divided into three major areas. In this talk, we focus on recent topics on metric fixed point theory and its applications, which will be very helpful to beginners and specialists of metric fixed point theory and its applications. Metric fixed point theory came from Banach's fixed point theorem . Because of its simplicity, usefulness and applications, it has become a very popular tools in solving the existence problems in many branches of mathematical analysis and applied sciences. Recently, it has been applied to economics, chemical engineering sciences, medicine, image recovery, electric engineering, game theory and other applied sciences by many authors. Recently, many authors have improved, extended and generalized Banach’s fixed point theorem in several ways. We will introduce two topics of these studies. One is how to generalize Banach’s contraction? The other one is how to extend Banach’s fixed point theorem in metric spaces to the large class of various generalized metric spaces?
