Precomplete clones on infinite sets which are closed under conjugation
Michael Pinsker
We show that on an infinite set, there exist no other precomplete clones closed under conjugation except those which contain all permutations. Since on base sets of some infinite c…

Clones containing all almost unary functions
Michael Pinsker
Let X be an infinite set of regular cardinality. We determine all clones on X which contain all almost unary functions. It turns out that independently of the size of X, these clon…

Maximal clones on uncountable sets that include all permutations
Michael Pinsker
We first determine the maximal clones on a set X of infinite regular cardinality which contain all permutations but not all unary functions, extending a result of Heindorf's for co…
