A Study on Interval-Valued Fuzzy Graph with Application in Energy Industry Management
Discrete Dynamics in Nature and Society, 2022 In this paper, we define the concept of level graphs on interval-valued fuzzy graphs (IVFGs) and introduce the notions of α,β−α,β− homomorphism, isomorphism, weak isomorphism, and co-weak isomorphism of IVFGs by α,β− homomorphism. Also, an application of

Globular multicategories with homomorphism types [PDF]
, 2023 We introduce various notions of globular multicategory with homomorphism types. We develop a higher dimensional modules construction that constructs globular multicategories with strict homomorphism types.

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 ...

A remark on rational Cherednik algebras and differential operators on the cyclic quiver [PDF]
, 2006 We show that the spherical subalgebra Uk,c of the rational Cherednik algebra associated to Sn 2 Cl, the wreath product of the symmetric group and the cyclic group of order l, is isomorphic to a quotient of the ring of invariant differential operators on ...

Homomorphic image orders on combinatorial structures [PDF]
, 2015 Combinatorial structures have been considered under various orders, including substructure order and homomorphism order. In this paper, we investigate the homomorphic image order, corresponding to the existence of a surjective homomorphism between two ...

Upper Cohen-Macaulay Dimension [PDF]
, 2004 In this paper, we define a homological invariant for finitely generated modules over a commutative noetherian local ring, which we call upper Cohen-Macaulay dimension.

Lattices of homomorphisms [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1986 AbstractGiven a variety K of lattice-ordered algebras, A ∈ K is catalytic if for all B ∈ K, K(A, B) is a lattice for the pointwise order. The catalytic objects are determined for various varieties of distributive-lattice-ordered algebras. The characterisations obtained do not show an overall unity and exhibit diverse behaviour.

Topological Multi-groups and Multi-fields [PDF]
, 2009 Topological groups, particularly, Lie groups are very important in differential geometry, analytic mechanics and theoretical physics. Applying Smarandache multi-spaces, topological spaces, particularly, manifolds and groups were generalized to ...

Continuity of homomorphisms and derivations from algebras of approximable and nuclear operators [PDF]
, 1994 1. Let be a Banach algebra. We say that homomorphisms from are continuous if every homomorphism from into a Banach algebra is automatically continuous, and that derivations from are continuous if every derivation from into a Banach -bimodule is ...

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.
