Zadeh's extension principle is applicable to functions defined upon elements of a set. A new extension principle is developed for functions defined upon power sets. Another extension is proposed for relations between sets, such as subsethood. A formal relation connects the two new extension principles. The new extension principles are not a consequences of Zadeh's original.
