IRREDUCIBLE COXETER GROUPS [PDF]
International Journal of Algebra and Computation, 2007 We prove that a non-spherical irreducible Coxeter group is (directly) indecomposable and that an indefinite irreducible Coxeter group is strongly indecomposable in the sense that all its finite index subgroups are (directly) indecomposable. Let W be a Coxeter group.

Decomposition of reductive regular prehomogeneous vector spaces [PDF]
, 2010 Let (G,V) be a regular prehomogeneous vector space (abbreviated to PV), where G is a connected reductive algebraic group over C. If $V= \oplus_{i=0}^{n}V_{i}$ is a decomposition of V into irreducible representations, then, in general, the PV's $(G,V_{i})$

Irreducible numerical semigroups [PDF]
Pacific Journal of Mathematics, 2003 A numerical semigroup is said to be irreducible whenever it can not be expressed as an intersection of two numerical semigroups containing it properly. The paper under review studies several aspects of these semigroups. In Section 1, the authors give a characterization of irreducible semigroups in terms of their Frobenius number.

2-irreducible and strongly 2-irreducible ideals of commutative rings [PDF]
, 2015 An ideal I of a commutative ring R is said to be irreducible if it cannot be written as the intersection of two larger ideals. A proper ideal I of a ring R is said to be strongly irreducible if for each ideals J, K of R, J\cap K\subseteq I implies that J\

Dynamic properties of the dynamical system SFnm(X), SFnm(f))
Applied General Topology, 2020 Let X be a continuum and let n be a positive integer. We consider the hyperspaces Fn(X) and SFn(X). If m is an integer such that n > m ≥ 1, we consider the quotient space SFnm(X). For a given map f : X → X, we consider the induced maps Fn(f) : Fn(X) → Fn(

Irreducible Radial Dislocation of the Proximal Interphalangeal Joint of a Finger
Journal of Orthopaedics, Trauma and Rehabilitation, 2015 Dislocations of the proximal interphalangeal joint (PIPJ) are often easily reduced with closed reduction and manipulation. Irreducible PIPJ dislocations are rare.

On α-Fuzzy Soft Irreducible Spaces
Al-Mustansiriyah Journal of Science, 2023 We define fuzzy soft irreducible sets, a-fuzzy soft irreducible sets in fuzzy soft topological spaces and study the properties including (fuzzy soft continuity; fuzzy soft homeomorphism and fuzzy soft topological properties) on a-fuzzy soft irreducible ...

Irreducible Subcube Partitions
The Electronic Journal of Combinatorics, 2023 A subcube partition is a partition of the Boolean cube $\{0,1\}^n$ into subcubes. A subcube partition is irreducible if the only sub-partitions whose union is a subcube are singletons and the entire partition. A subcube partition is tight if it “mentions” all coordinates.

Representations of the cyclically symmetric q-deformed algebra $so_q(3)$
, 1998 An algebra homomorphism $\psi$ from the nonstandard q-deformed (cyclically symmetric) algebra $U_q(so_3)$ to the extension ${\hat U}_q(sl_2)$ of the Hopf algebra $U_q(sl_2)$ is constructed.
