Abstract

This paper studies maximality and totality of stable functions in the category of stable bifinite domains. We present three main results as follows,o(1)every maximum-preserving function is a maximal element in the stable function spaces; (2)a maximal stable function f : D - E is maximum-preserving if D is maximum-separable and E is completely separable; and (3)a stable bifinite domain D is maximum-separable if and only if for any locally distributive stable bifinite domain E, each maximal stable function f : D - E is maximum-preserving.
