Decomposition of reductive regular prehomogeneous vector spaces [PDF]

open access: yes, 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 $(G,V_{i})$

The irreducible photon [PDF]

open access: yes, 2009
In recent years it has become evident that the primary concept of the photon has multiple interpretations, with widely differing secondary connotations.

Dynamic properties of the dynamical system SFnm(X), SFnm(f))

open access: yesApplied 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(

On Irreducible Maps and Slices [PDF]

open access: yesCombinatorics, Probability and Computing, 2014
We consider the problem of enumeratingd-irreducible maps,i.e., planar maps all of whose cycles have length at leastd, and such that any cycle of lengthdis the boundary of a face of degreed. We develop two approaches in parallel: the natural approach via substitution, where these maps are obtained from general maps by a replacement of alld-cycles by ...

Irreducible Radial Dislocation of the Proximal Interphalangeal Joint of a Finger

open access: yesJournal 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

open access: yesAl-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 triangulations are small [PDF]

open access: yesJournal of Combinatorial Theory, Series B, 2010
A triangulation of a surface is \emph{irreducible} if there is no edge whose contraction produces another triangulation of the surface. We prove that every irreducible triangulation of a surface with Euler genus $g\geq1$ has at most $13g-4$ vertices. The best previous bound was $171g-72$.

Role of Posterior Interfacetal Distraction and Grafting in Complex Atlantoaxial Dislocation

open access: yesEgyptian Spine Journal, 2019
Background Data: Atlantoaxial fixation, unlike subaxial spine, is still challenging due to complex topographical anatomy. Nowadays, atlas lateral mass screws and transpedicular axis screws fixation is a well-accepted technique for the management of ...
