We investigate finitary functions from $\mathbb{Z}_{pq}$ to $\mathbb{Z}_{pq}$ for two distinct prime numbers $p$ and $q$. We show that the lattice of all clones on the set $\mathbb{Z}_{pq}$ which contain the addition of $\mathbb{Z}_{pq}$ is finite. We provide an upper bound for the cardinality of this lattice through an injective function to the direct product of the lattice of all $(\mathbb{Z}_p,\mathbb{Z}_q)$-linearly closed clonoids to the $p+1$ power and the lattice of all $(\mathbb{Z}_q…

Closed Function Sets on Groups of Prime Order

There are infinitely many non finitely generated clones above $\operatorname{Clo}({\mathbb{ Z}_p \times \mathbb(Z)_p, +})$ for $p > 2$.

It is shown that the independence of finitely generated varieties with edge term can be decided by a polynomial time algorithm.

It is proved that, on a set of size n, the number of clones that contain a group operation and all constant functions is finite if n is squarefree, and refutes a second conjecture from [5].

It is shown that the number of clones on a k element set that contain a Mal'tsev operation and all k constants is finite iff k≤3. This answers a part of a question of Ralph McKenzie and Ivo Rosenberg

Polynomial clones on groups of order pq

For two distinct primes p, q, we describe those clones on a set of size pq that contain a given group operation and all constant operations. We show that each such clone is determined by congruences

The complexity of constraint satisfaction : an algebraic approach.

An algebraic approach has proved to be very successful in studying the complexity of constraint problems and can be represented as constraint satisfaction and optimization problems.
