Semilattices of stratified extensions
Grillet (Semigroup Forum 50:25–36, 1995) introduced the concept of stratified semigroups as a kind of generalisation of finite nilsemigroups. We...

Unramified Heisenberg group extensions of number fields
We construct étale generalized Heisenberg group covers of hyperelliptic curves over number fields. We use these to produce infinite families of...

Theorems of the Alternative Revisited and Some Extensions of Yuan’s Lemma
In this paper we deal with theorems of the alternative for systems of inequalities. Precisely, we give a formulation that encompasses several known...

The Voisin map via families of extensions
Let Y be a cubic fourfold not containing any plane, F ( Y ) be the variety of lines in Y , Z ( Y ) be the Lehn-Lehn-Sorger-van Straten hyperkähler eightfold...

A Method for Automatic Search for Families of Optimal Chordal Ring Networks
AbstractArden and Lee proposed a class of chordal ring networks of degree three as communication networks for multicomputer systems, derived a...

Commutative Ring Extensions Defined by Perfect-Like Conditions
In 2005, Enochs, Jenda, and López-Romos extended the notion of perfect rings to n -perfect rings such that a ring is n -perfect if every flat module...

Homogenized skew PBW extensions
In this paper, we provide a new and more general filtration to the family of noncommutative rings known as skew PBW extensions. We introduce the...

Filter pairs and natural extensions of logics
We adjust the notion of finitary filter pair, which was coined for creating and analyzing finitary logics, in such a way that we can treat logics of...

Birational geometry of smooth families of varieties admitting good minimal models
We study families of projective manifolds with good minimal models. After constructing a suitable moduli functor for polarized varieties with...

Separate families of fuzzy dominated nonlinear operators with applications
This paper presents novel fixed-point results for two distinct families of fuzzy-dominated operators satisfying a generalized nonlinear contraction...

Hodge sheaves underlying flat projective families
We show that, for any fixed weight, there is a natural system of Hodge sheaves, whose Higgs field has no poles, arising from a flat projective family...

Extensions of Analytic and Pluriharmonic Functions in Given Directions by the Chirka Method: a Survey
In this paper, we provide a survey of results on analytic and plurisubharmonic extensions of functions that have a thin set of singularities along a...

Non-disjoint strong external difference families can have any number of sets
Strong external difference families (SEDFs) are much-studied combinatorial objects motivated by an information security application. A well-known...

On Equicontinuity of the Families of Map**s with One Normalization Condition in Terms of Prime Ends
We study map**s with branching satisfying certain conditions of distortion for the modulus of families of paths. Under the conditions that the...

Rigidity of generalized Veech 1969/Sataev 1975 extensions of rotations
We look at d -point extensions of a rotation of angle α with r marked points, generalizing the examples of Veech 1969 and Sataev 1975, together with...

Three infinite families of chiral 4-polytopes with symmetric automorphism groups
In this paper, we give three infinite families of chiral 4-polytopes, with the automorphism group of each member of a family being symmetric. This...
