Functions which are defined on finite sets occur in almost all fields of mathematics. For more
than 80 years algebras whose universes are such functions (so-called function algebras) …

This article describes the lattice of varieties generated by those of flocks and near heaps.
Flocks and heaps are two ways of presenting groups by a ternary operation rather than a …

We investigate the interval $ I (p^ 3) $ in the lattice of clones on the ring $\mathbb {Z} _ {p^ 3}
$ between the clone of polynomial operations and the clone of congruence preserving …

We investigate the lattice I (n) of clones on the ring Z_n between the clone of polynomial
functions and the clone of congruence preserving functions. The crucial case is when n is a …

Publisher Summary This chapter elaborates different aspects of affine modules. It discusses
the reducts of modules. The chapter presents the characterization of certain reducts of …

The article is devoted to classification of closed sets of functions in k-valued logic. We build
the classification of finite closed sets. The sets contain only constants and one-ary functions …

Iterating a set of R-linear forms (R denotes a commutative ring with 1) one obtains new such
forms. For example, starting withf (x, y)= xY, one obtains gCw, z)= fUW9,~ CW))=~-~ Y+ Z …

In the present, third survey of reviews of articles on Abelian groups are included papers
reviewed during 1972–1978. Here, as in the previous surveys, the questions concerning …
