The Order of Generalized Hypersubstitutions of Type τ=(2) [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
The order of hypersubstitutions, all idempotent elements on the monoid of all hypersubstitutions of type τ=(2) were studied by K. Denecke and Sh. L. Wismath and all idempotent elements on the monoid of all hypersubstitutions of type τ=(2,2) were studied ...

Green’s Relations on Submonoids of Generalized Hypersubstitutions of Type (n) [PDF]

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
A generalized hypersubstitution of type τ = (n) is a function which takes the n-ary operation symbol f to the term of the same type σ(f ) which does not necessarily preserve the arity. Let HypG(n) be the set of all these generalized hypersubstitutions of

Idempotent Elements of Weak Projection Generalized Hypersubstitutions [PDF]

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
A generalized hypersubstitution of type τ = (ni)i∈I is a mapping σ which maps every operation symbol fi to the term σ (fi) and may not preserve arity.

The Depth of Generalized Full Terms and Generalized Full Hypersubstitutions [PDF]

open access: yesAlgebra, 2013
We generalize the concept of a full term which was introduced by Denecke and Changphas and the concept of the depth of a hypersubstitution which was introduced by Denecke et al. to the depth of a generalized full term and the depth of a generalized full hypersubstitution and then derive the formular for its depth.

On Partial Clones of K-Terms

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2021
The main purpose of this paper is to generalize the concept of linear terms. A linear term is a term in which every variable occurs at most once. K. Denecke defined partial operations on linear terms and partial clones.

All intra-regular generalized hypersubstitutions of type (2) [PDF]

open access: yesActa Universitatis Sapientiae, Mathematica, 2019
AbstractA generalized hypersubstitution of type τ maps each operation symbol of the type to a term of the type, and can be extended to a mapping defined on the set of all terms of this type. The set of all such generalized hypersubstitutions forms a monoid. An element a of a semigroup S is intra-regular if there is b ∈ S such that a = baab.

The Order of Hypersubstitutions of Type (2,1)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2011, Issue 1, 2011., 2011
Hypersubstitutions are mappings which map operation symbols to terms of the corresponding arities. They were introduced as a way of making precise the concept of a hyperidentity and generalizations to M‐hyperidentities. A variety in which every identity is satisfied as a hyperidentity is called solid.

All Maximal Completely Regular Submonoids of HypG(2)

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
In this paper we consider mappings σ which map the binary operation symbol f to the term σ (f) which do not necessarily preserve the arity. These mapping are called generalized hypersubstitutions of type τ = (2) and we denote the set of all these ...

Unsolid and fluid strong varieties of partial algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2006, Issue 1, 2006., 2006
A partial algebra 𝒜=(A;(fiA) i∈I) consists of a set A and an indexed set (fiA) i∈I of partial operations fiA:Ani⊸→A. Partial operations occur in the algebraic description of partial recursive functions and Turing machines. A pair of terms p ≈ q over the partial algebra 𝒜 is said to be a strong identity in 𝒜 if the right‐hand side is defined whenever ...
