The ring of regular functions of an algebraic monoid [PDF]

open access: yesTransactions of the American Mathematical Society, 2011
Let M be an irreducible normal algebraic monoid with unit group G. It is known that G admits a Rosenlicht decomposition, G=G_antG_aff, where G_ant is the maximal anti-affine subgroup of G, and G_aff the maximal normal connected affine subgroup of G. In this paper we show that this decomposition extends to a decomposition M=G_antM_aff, where M_aff is ...

The X[[S]]-Sub-Exact Sequence of Generalized Power Series Rings

open access: yesAl-Jabar, 2020
Let  be a ring,  a strictly ordered monoid, and K, L, M are R-modules. Then, we can construct the Generalized Power Series Modules (GPSM) K[[S]], L[[S]], and M[[S]], which are the module over the Generalized Power Series Rings (GPSR) R[[S]].

FOR WHICH PUISEUX MONOIDS ARE THEIR MONOID RINGS OVER FIELDS AP?

open access: yesInternational Electronic Journal of Algebra, 2020
A Puiseux monoid is a submonoid of the set of nonnegative rational numbers under addition. For a monoid \(M\), a field \(F\) and a symbol \(X\), the set \(F[X;M]=\bigoplus_{m\in M}F X^m\), is the semigroup ring associated to \(M\); addition is performed component wise, and multiplication follows by the distributive law and the rule \(X^mX^n=X^{m+n ...

When Are Graded Rings Graded S-Noetherian Rings

open access: yesMathematics, 2020
Let Γ be a commutative monoid, R=⨁α∈ΓRα a Γ-graded ring and S a multiplicative subset of R0. We define R to be a graded S-Noetherian ring if every homogeneous ideal of R is S-finite. In this paper, we characterize when the ring R is a graded S-Noetherian

Endomorphisms of Some Groupoids of Order $k+k^2$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
Automorphisms and endomorphisms are actively used in various theoretical studies. In particular, the theoretical interest in the study of automorphisms is due to the possibility of representing elements of a group by automorphisms of a certain algebraic ...

SEMIRING

open access: yesBarekeng, 2011
Dalam aljabar, semiring merupakan suatu struktur yang serupa dengan ring, tetapi tanpa syarat bahwa setiap elemen harus memiliki invers terhadap operasi penjumlahan. Jika pada ring, R,  adalah grup komutatif atau grup abelian maka pada semiring, S, 

ON ANNIHILATOR IDEALS OF SKEW MONOID RINGS [PDF]

open access: yesGlasgow Mathematical Journal, 2009
AbstractA ring R is called a left APP-ring if the left annihilator lR(Ra) is pure as a left ideal of R for every a ∈ R; R is called (left principally) quasi-Baer if the left annihilator of every (principal) left ideal of R is generated by an idempotent. Let R be a ring and M an ordered monoid.

The Steinberg group of a monoid ring, nilpotence, and algorithms [PDF]

open access: yes, 2007
For a regular ring R and an affine monoid M the homotheties of M act nilpotently on the Milnor unstable groups of R[M]. This strengthens the K2 part of the main result of [J.

Identifying Low-Frequency Tree-Ring Variation

open access: yes, 1991
I propose an approach to provide 95% confidence intervals for a chronology of low-frequency tree-ring variation so that a level of significance or importance for trends can be inferred.
