A Dual of the Compression-Expansion Fixed Point Theorems

A Dual of the Compression-Expansion Fixed Point Theorems

This paper presents a dual of the fixed point theorems of compression and expansion of functional type as well as the original Leggett-Williams fixed point theorem. The multi-valued situation is also discussed.
