Binary relations on the monoid of V-proper hypersubstitutions [PDF]

open access: yes, 2006
In this paper we consider different relations on the set P(V) of all proper hypersubstitutions with respect to a given variety V and their properties. Using these relations we introduce the cardinalities of the corresponding quotient sets as degrees and ...

M-solid generalized non-deterministic varieties [PDF]

open access: yes, 2016
A generalized non-deterministic hypersubstitution is a mapping which maps operation symbols of type τ to the set of terms of the same type which does not necessarily preserve the arity.

Generalized Abstracted Mean Values [PDF]

open access: yes, 1998

GENERALIZED DERIVED ALGEBRAS AND GENERALIZED INDUCED ALGEBRAS

open access: yes, 2010
Substituting for the fundamental operations of an algebra term operations we get a new algebra of the same type, called a generalized derived algebra. Such substitutions are called generalized hypersubstitutions.

3D simulation of laminated shell structures using the Proper Generalized Decomposition [PDF]

open access: yes, 2014
Numerical simulations of composite structures are generally performed using multi-layered shell elements in the context of the finite elements method. This strategy has numerous advantages like a low computation time and the capability to reproduce the ...

Idempotence and regularity of generlized relational hypersubstitutions for algebraic sytems [PDF]

open access: yes
The concept of a generalized relational hypersubstitution for algebraic systems of type $(\tau,\tau')$ is an extension of the concept of a generalized hypersubstitution for universal algebra of type $\tau$.

Valuations and Generalized Hypersubstitutions

open access: yes, 2014
Generalized hypersubstitutions were introduced by S. Leeratanavalee and K. Denecke as a way of making precise the concepts of strong hyperidentity and M- strong hyperidentity. A variety V is called M- strongly solid if every identity of V is an M- strong

All completely regular elements in $Hyp_{G}(n)$ [PDF]

open access: yes, 2013
In Universal Algebra, identities are used to classify algebras into collections, called varieties and hyperidentities are use to classify varieties into collections, called hypervarities.

Pre-strongly solid varieties of commutative semigroups [PDF]

open access: yes, 2011
Generalized hypersubstitutions are mappings from the set of all fundamental operations into the set of all terms of the same language do not necessarily preserve the arities.

Generalized permutation patterns - a short survey [PDF]

open access: yes, 2010
An occurrence of a classical pattern p in a permutation π is a subsequence of π whose letters are in the same relative order (of size) as those in p.
