All Maximal Idempotent Submonoids of Generalized Cohypersubstitutions of Type τ = (2)
A generalized cohypersubstitution of type τ is a mapping σ which maps every ni-ary cooperation symbol fi to the coterm σ(f ) of type τ = (ni)i∈I. Denote by CohypG(τ) the set of all generalized cohypersubstitutions of type τ.

On extensions of completely simple semigroups by groups [PDF]
An example of an extension of a completely simple semigroup U by a group H is given which cannot be embedded into the wreath product of U by H. On the other hand, every central extension of U by H is shown to be embeddable in the wreath product of U by H,

On an equivalence between regular ordered Γ-semigroups and regular ordered semigroups
In this paper, we develop a technique which enables us to obtain several results from the theory of Γ-semigroups as logical implications of their semigroup theoretical analogues.

Quasi-ideal Ehresmann transversals: The spined product structure
In any U-abundant semigroup with an Ehresmann transversal, two significant components R and L are introduced in this paper and described by Green’s ∼\sim -relations.

The product of quasi-ideal refined generalised quasi-adequate transversals
As the real common generalisations of both orthodox transversals and adequate transversals in the abundant case, the concept of refined generalised quasi-adequate transversal, for short, RGQA transversal was introduced by Kong and Wang. In this paper, an

Almost factorizable weakly type B semigroups
The definition of an almost left factorizable weakly type B semigroup is introduced by using the notion of a left factorizable weakly type B monoids, and some properties and characterizations on such semigroup are obtained.

The notion of the graphon (a symmetric measurable fuzzy set of $[0, 1]^2$) was introduced by L. Lov\'asz and B. Szegedy in 2006 to describe limit objects of convergent sequences of dense graphs.

Recursive POD expansion for reaction-diffusion equation [PDF]
This paper focuses on the low-dimensional representation of multivariate functions. We study a recursive POD representation, based upon the use of the power iterate algorithm to recursively expand the modes retained in the previous step.

Idempotent Elements of Weak Projection Generalized Hypersubstitutions
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.

Application of (m, n)-Г-Hyperideals in Characterization of LA-Г-Semihypergroups
In this paper, we study the concept of ordered (m, n)-Г-hyperideals in an ordered LA-Г-semihypergroup. We show that if (S, Г, ◦,⩽) is a unitary ordered LA-Г-semihypergroup with zero 0 and satisfies the hypothesis that it contains no non-zero nilpotent (m,
