Universal finitary codes with exponential tails
, 2005 In 1977, Keane and Smorodinsky showed that there exists a finitary homomorphism from any finite-alphabet Bernoulli process to any other finite-alphabet Bernoulli process of strictly lower entropy.

Bounded cohomology of groups acting on trees with almost prescribed local actions
Bulletin of the London Mathematical Society, EarlyView.Abstract We prove the vanishing of bounded cohomology of the groups acting on trees with almost prescribed local actions G(F,F′)$G(F, F^{\prime })$, where F

Distributive and Dual Distributive Elements in Hyperlattices
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 In this paper we introduce and study distributive elements, dual distributive elements in hyperlattices, and prove that these elements forms ∧-semi lattice and ∨-semi hyperlattice, respectively.

Finite models for positive combinatorial and exponential algebra
Bulletin of the London Mathematical Society, EarlyView.Abstract We use high girth, high chromatic number hypergraphs to show that there are finite models of the equational theory of the semiring of non‐negative integers whose equational theory has no finite axiomatisation, and show this also holds if factorial, fixed base exponentiation and operations for binomial coefficients are adjoined.

Factoring Continuous Homomorphisms Defined on Submonoids of Products of Topologized Monoids
Axioms, 2019 We study factorization properties of continuous homomorphisms defined on submonoids of products of topologized monoids. We prove that if S is an ω-retractable submonoid of a product D = ∏ i ∈ I D i of topologized monoids ...

On skew derivations as homomorphisms or anti-homomorphisms [PDF]
Commentationes Mathematicae Universitatis Carolinae, 2016 Let $R$ be a prime ring with center $Z$ and $I$ be a nonzero ideal of $R$. In this manuscript, we investigate the action of skew derivation $(\delta,\varphi)$ of $R$ which acts as a homomorphism or an anti-homomorphism on $I$. Moreover, we provide an example for semiprime case.

Fundamental Homomorphism Theorems for Neutrosophic Extended Triplet Groups
Symmetry, 2018 In classical group theory, homomorphism and isomorphism are significant to study the relation between two algebraic systems. Through this article, we propose neutro-homomorphism and neutro-isomorphism for the neutrosophic extended triplet group (NETG ...

The Tannakian Formalism and the Langlands Conjectures
, 2010 Let H be a connected reductive group over an algebraically closed field of characteristic zero, and let G be an abstract group. In this note we show that every homomorphism from the Grothendieck semiring of H to that of G which maps irreducible ...

Growth problems in diagram categories
Bulletin of the London Mathematical Society, EarlyView.Abstract In the semisimple case, we derive (asymptotic) formulas for the growth rate of the number of summands in tensor powers of the generating object in diagram/interpolation categories.

Homomorphisms and amalgamation
Discrete Mathematics, 2003 A graph \(G\) is called core if each homomorphism \(G \to G\) is an automorphism of \(G\). A graph \(H\) is called \(G\)-colourable if there is a homomorphism \(H \to G\). The author proves that if \(G\) is a finite core, then the class of \(G\)-colourable graphs is a pseudo-amalgamation class in the sense of \textit{R.
