Abstract |
|
We prove the following result in this paper: Let (X,d) be a complete metric space and Y be a space having the fixed point property. Let f : X × Y → X × Y be a continuous map. If f is a contraction mapping in the first variable, then f has a fixed point. This result is a generalization to the result obtained in Nadler [5]. Other results are proved concerning the fixed point theorem for product spaces. The concept “continuous height-selection” is discussed and its relation to the existence of fixed points for a function is also discussed. |
