The irreducible representations of the double cover of SL(m) with infinitesmal character 1p having a maximal primitive ideal are determined. We investigate whether these representations are attached to a nilpotent orbit and use the orbit method to speculate their K types. We conclude with a character formula expressing the representations as a sum of simpler virtual representions. Thesis Superv...

the rings considered in this article are commutative with identity $1neq 0$. by a proper ideal of a ring $r$,  we mean an ideal $i$ of $r$ such that $ineq r$.  we say that a proper ideal $i$ of a ring $r$ is a  maximal non-prime ideal if $i$ is not a prime ideal of $r$ but any proper ideal $a$ of $r$ with $ isubseteq a$ and $ineq a$ is a prime ideal. that is, among all the proper ideals of $r$,...

Symmetric cryptography offers high computational efficiency, since it does not rely on expensive operations such as modular exponentiation or cryptographic pairing. Moreover, it offers compact authentication tags, proportional to the size of underlying primitive, for instance 160-bit with SHA1 based HMAC and 128-bit for AES-based MACs. Finally, key sizes are small and almost optimal, which offe...

Abstract. The generalized Effros-Hahn conjecture for groupoid C-algebras says that, if G is amenable, then every primitive ideal of the groupoid Calgebra C(G) is induced from a stability group. We prove that the conjecture is valid for all second countable amenable locally compact Hausdorff groupoids. Our results are a sharpening of previous work of Jean Renault and depend significantly on his ...

We extend to arbitrary commutative base rings a recent result of Demeneghi that every ideal an ample groupoid algebra over field is intersection kernels induced representations from isotropy groups, with much shorter proof, by using the author's Disintegration Theorem for representations. also prove primitive kernel representation group; however, we are unable show, in general, it irreducible r...

conclusions pnet/ews should be included in the differential diagnosis of renal tumors in symptomatic young adults. patients with localised pnet/ews treated with a combination of surgery and chemotherapy have an excellent chance of long-term survival, as in the case we have presented. introduction primitive neuroectodermal tumor (pnet)/ewing’s sarcoma (ews) belongs to a family of neoplasms that ...

This paper offers an expository account of some ideas, methods, and conjectures concerning quantized coordinate rings and their semiclassical limits, with a particular focus on primitive ideal spaces. The semiclassical limit of a family of quantized coordinate rings of an affine algebraic variety V consists of the classical coordinate ring O(V ) equipped with an associated Poisson structure. Co...

Local metal-poor galaxies stand as ideal laboratories for probing the properties of interstellar medium (ISM) in chemically unevolved conditions. Detailed studies this primitive ISM can help gain insights into physics first primordial that may be responsible reionization. Quantifying porosity to ionizing photons nearby improve our understanding mechanisms leading Lyman continuum photon leakage ...

let $l$ be a completely regular frame and $mathcal{r}l$ be the ‎ring of continuous real-valued functions on $l$‎. ‎we show that the‎ ‎lattice $zid(mathcal{r}l)$ of $z$-ideals of $mathcal{r}l$ is a‎ ‎normal coherent yosida frame‎, ‎which extends the corresponding $c(x)$‎ ‎result of mart'{i}nez and zenk‎. ‎this we do by exhibiting‎ ‎$zid(mathcal{r}l)$ as a quotient of $rad(mathcal{r}l)$‎, ‎the‎ ‎...
