We deal with varieties with one basic operation f(x1,...,xn) and one defining identity f(x1,..., xn) = f(xπ(1),...,xπ(n)), where π is a permutation whose cyclic set consists of distinct primes p1,...,pr, with the sum p1+...+pr = n. Their interpret

Let Π be the set of all primes, $$\mathbb{A}$$ the field of all algebraic numbers, and Z the set of square-free natural numbers. We consider partially ordered sets of interpretability types such as $$\mathbb{L}_\Pi = (\{ [AD_\Gamma ]|\Gamma \subsete

For integers 1 ≤ m < n, a Cantor variety with m basic n-ary operations ωi and n basic m-ary operations λk is a variety of algebras defined by identities λk(ω1(\(x\)), ... , ωm(\(\bar x\))) = \(x\)k and ωi(λ1(\(\bar y\)), ... ,λn(\(\bar y\))

It is proved that for every regular variety V of algebras, an interpretability type [V] in the lattice \({\mathbb{L}^{\operatorname{int} }} \) is primary w.r.t. intersection, and so has at most one covering. Moreover, the sole covering, if any, for [

Let\(\mathbb{S}_n \) be a symmetric group on a set {1,2,...,n}. For an arbitrary permutation π of\(\mathbb{S}_n \), we consider a variety n G π ofn-groupoids (A, f) satisfying the identityf(x 1,x 2,...,x n )=f(x π(1),x π(2)...,x π(n)). It is pro

Let Abd be a variety of Abelian groups of a finite exponent d≥1 and SC (Abd) be the set of all strong Mal’tsev conditions satisfied in Abd. We define the concept of a η-basis in SC(Abd) in terms of a basis w.r.t. a class η of varieties with com

The dimension of a variety V of algebras is the greatest length of a basis (i.e., of an independent generating set) for an SC-theory SC(V), consisting of strong Mal'tsev conditions satisfied in V. The variety V is assumed infinite-dimensional if the

A dimension of a finitely based variety V of algebras is the greatest length of a basis (that is, an independent generating set) for the SC-theory SC(V) with the strong Mal'tsev conditions satisfied in V. A dimension is said to be infinite if the len
