Recently, we improved our long-standing Metatheorem in Fixed Point Theory.
In this paper, as its applications, some well-known order theoretic fixed point theo-
rems are equivalently formulated to existence theorems on maximal elements, com-
mon fixed points, common stationary points, and others. Such theorems are the
ones due to Banach, Nadler, Browder-Göhde-Kirk, Caristi-Kirk, Caristi, Brøndsted,
and possibly many others.
