A note on the homomorphism theorem for hemirings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
The fundamental homomorphism theorem for rings is not generally applicable in hemiring theory. In this paper, we show that for the class of N-homomorphism of hemirings the fundamental theorem is valid.

A remark on rational Cherednik algebras and differential operators on the cyclic quiver [PDF]

open access: yes, 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]

open access: yes, 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 ...

Topological applications of graded Frobenius $n$-homomorphisms, II [PDF]

open access: yesTransactions of the Moscow Mathematical Society, 2011
This paper is divided into three parts. In the first part the author generalizes the work of V. M. Buchstaber and E. G. Rees on Frobenius \(n\)-homomorphisms to the case of graded algebras. In the second part the author applies the new algebraic technique of Frobenius \(n\)-homomorphisms to find estimates on the cohomological length of the base and the

Upper Cohen-Macaulay Dimension [PDF]

open access: yes, 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.

Properties of neutrosophic κ-ideals in subtraction semigroups G [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
Our aim is to explore the idea of neutrosophic N-ideals in near-subtraction semigroups in this article and obtain some outcomes that are equivalent to them. We also illustrate the notion of a neutrosophic κ-intersection.

Topological Multi-groups and Multi-fields [PDF]

open access: yes, 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 ...

Homomorphism Obstructions For Satellite Maps [PDF]

open access: yes, 2023
A knot in a solid torus defines a map on the set of (smooth or topological) concordance classes of knots in S³. This set admits a group structure, but a conjecture of Hedden suggests that satellite maps never induce interesting homomorphisms: we give new
