On sets related to maximal clones
Klaus Denecke, Yeni Susanti · Discussiones Mathematicae - General Algebra and Applications · 2012
For an arbitrary h-ary relation we are interested to express n-clone Pol n in terms of some subsets of the set of all n-ary operations O n (A) on a nite set A, which are in general not clones but we can obtain Pol n from these sets by using intersection and union. Therefore we specify the concept a function preserves a relation and moreover, we study the properties of this new concept and the connection between these sets and Pol n . Particularly we study R n;k;b for arbitrary partial order relations, equivalence relations and
