EMS Surveys in Mathematical Sciences, 2021 Torelli groups are subgroups of mapping class groups that consist of those diffeomorphism classes that act trivially on the homology of the associated closed surface. The Johnson homomorphism, defined by Dennis Johnson, and its generalization, defined by S. Morita, are tools for understanding Torelli groups.

Some Brunn-Minkowski type inequalities for L p $L_{p}$ radial Blaschke-Minkowski homomorphisms
Journal of Inequalities and Applications, 2016 Schuster introduced radial Blaschke-Minkowski homomorphisms. Recently, they were generalized to L p $L_{p}$ radial Blaschke-Minkowski homomorphisms by Wang et al.

Duality for powerset coalgebras [PDF]
Logical Methods in Computer Science, 2022 Let CABA be the category of complete and atomic boolean algebras and complete boolean homomorphisms, and let CSL be the category of complete meet-semilattices and complete meet-homomorphisms. We show that the forgetful functor from CABA to CSL has a left

Weakly linear homomorphisms in skew boolean modules [PDF]
Journal of Hyperstructures, 2015 In this paper we introduce the notion of linear, weakly linear and strongly linear homomorphisms between two Skew Boolean modules and obtain various properties. We also introduce a scalar multiplication on the set of all weakly linear homomorphisms (wHom(

Journal of Computer and System Sciences, 2012 The homomorphism problem for relational structures is an abstract way of formulating constraint satisfaction problems (CSP) and various problems in database theory. The decision version of the homomorphism problem received a lot of attention in literature; in particular, the way the graph-theoretical structure of the variables and constraints ...

On the Homomorphisms of the Lie Groups and
Abstract and Applied Analysis, 2013 We first construct all the homomorphisms from the Heisenberg group to the 3-sphere. Also, defining a topology on these homomorphisms, we regard the set of these homomorphisms as a topological space.

Images of formal matrices of elements of matrix groups over associative rings
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020 The paper substantiates the image by formal matrices of some elements of linear groups over associative rings by using the properties of redundant and fixed modules.

Some categorical aspects of BCH-algebras
International Journal of Mathematics and Mathematical Sciences, 2003 We show that the category BCH of BCH-algebras and BCH-homomorphisms is complete. We also show that it has coequalizers, kernel pairs, and an image factorization system. It is also proved that onto homomorphisms and coequalizers, and monomorphisms and one-

Mathematics, 2020 In this article, we investigate the fundamental properties of coalgebras with coalgebra comultiplications, counits, and coalgebra homomorphisms of coalgebras over a commutative ring R with identity 1R based on digital images with adjacency relations.

Lattice Homomorphisms Induced by Group Homomorphisms [PDF]
Proceedings of the American Mathematical Society, 1951 Introduction. By a lattice homorphism of a group G onto a group G' we mean a single-valued mapping sb of the lattice L(G) of subgroups of G onto the lattice L(G') of subgroups of G', which preserves all unions and intersections, that is, which is subject to the conditions 1. (U,S,)(k U= (S,(k), 2.
