Fixed points for discontinuous quasi-monotone maps in rn
Let Kbe the unit cube in Rn an;… (/i, /a/): Kn -* Rn. It is known tha;…as maximal and minimal fixed points in Kn if /: Kn Kn an;…s monotone increasing. In this paper;…eaker condition, namely quasi-monotonicity, is considered and it is proved that the above mentioned conclusion is still true i;…s either quasi-monotone. © 1988 American Mathematical Society.
