Monoid presentations and associated groupoids

open access: yes, 1998
We consider properties of a 2-complex associated by Squier to a monoid presentation. We show that the fundamental groupoid admits a monoid structure, and we establish a relationship between its group completion and the fundamental group of the 2-complex.

The isomorphism problem for commutative monoid rings

open access: yes, 1998
By substantial changes and corrections in Demushkin's old paper the essentially final positive answer to the isomorphism problem for monoid rings of submonoids of Zr is obtained.

The Hopf monoid of orbit polytopes

open access: yes, 2020
Many families of combinatorial objects have a Hopf monoid structure. Aguiar and Ardila introduced the Hopf monoid of generalized permutahedra and showed that it contains various other notable combinatorial families as Hopf submonoids, including graphs ...

Hilbert series of right-angled affine Artin monoid $M(\widetilde{A}^{\infty}_{n})$

open access: yesKuwait Journal of Science, 2017
It is already proved that the growth rate of all the spherical Artin monoids is less than 4. In this paper, we find the Hilbert series of the associated right-angled affine Artin monoid M and also we discuss the recurrence relations and the growth of ...

On Ideals of Submonoids of Power Monoids

open access: yesMathematics
Let S be a numerical monoid, while a Pfin(S)-monoid S is a monoid generated by a finite number of finite non-empty subsets of S. That is, S is a non-cancellative commutative monoid obtained from the sumset of finite non-negative integer sets.

Algebraic Structures Of Neutrosophic Soft Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2015
In this paper, we study the algebraic operations of neutrosophic soft sets and their basic properties associated with these opertaions. And also define the associativity and distributivity of these operations.

Monoid of Multisets and Subsets

open access: yes, 2003
The monoid of functions yielding elements of a group is introduced. The monoid of multisets over a set is constructed as such monoid where the target group is the group of natural numbers with addition.

Monoid Congruences, Binomial Ideals, and Their Decompositions [PDF]

open access: yes, 2014
This dissertation refines and extends the theory of mesoprimary decomposition, as introduced by Kahle and Miller. We begin with an overview of the existing theory of mesoprimary decomposition in both the combinatorial setting of monoid congruences and ...

The Planar Rook Monoid

open access: yes, 2006
Pascal\u27s triangle is a very important structure in combinatorics: its entries, the binomial coefficients, answer a number of counting-related questions. I will define a set of functions, the Planar Rook monoid, whose structure is tied to Pascal\u27s
