EL SISTEMA PENITENCIARI CATALÀ: FONAMENT I EXERCICI DE LA COMPETÈNCIA [PDF]

, 2016
Catalunya té atribuïda per l’Estatut d’autonomia la competència executiva en matèria penitenciària. Aquest fet, singular a l’Estat espanyol i amb pocs exemples anàlegs en altres països, ha plantejat, des del punt de vista jurídic, el problema de ...

Sharp Bounds for Neuman Means in Terms of Geometric, Arithemtic and Quadratic Means [PDF]

arXiv, 2014
In this paper, we find the greatest values $\alpha_{1}$, $\alpha_{2}$, $\alpha_{3}$, $\alpha_{4}$, $\alpha_{5}$, $\alpha_{6}$, $\alpha_{7}$, $\alpha_{8}$ and the least values $\beta_{1}$, $\beta_{2}$, $\beta_{3}$, $\beta_{4}$, $\beta_{5}$, $\beta_{6}$, $\beta_{7}$, $\beta_{8}$ such that the double inequalities $$A^{\alpha_{1}}(a,b)G^{1-\alpha_{1}}(a,b)<

Singular Hochschild Cohomology and Gerstenhaber Algebra Structure [PDF]

arXiv, 2015
In this paper, we define the singular Hochschild cohomology groups $HH_{sg}^i(A, A)$ of an associative $k$-algebra $A$ as morphisms from $A$ to $A[i]$ in the singular category $D_{sg}(A\otimes_k A^{op})$ for $i\in \mathbb{Z}$. We prove that $HH_{sg}^*(A, A)$ has a Gerstenhaber algebra structure and in the case of a symmetric algebra $A$, $HH_{sg}^*(A ...

On Nilary Group Rings [PDF]

arXiv, 2014
In a ring $A$ an ideal $I$ is called (principally) nilary if for any two (principal) ideals $V, W$ in $A$ with $VW\subseteq I,$ then either $V^n\subseteq I$ or $W^m\subseteq I,$ for some positive integers $m$ and $n$ depending on $V$ and $W;$ a ring $A$ is called (principally) nilary if the zero ideal is a (principally) nilary ideal~\cite ...

A large gap in a dilate of a set [PDF]

arXiv, 2020
Let $A \subset \mathbb{F}_p$ with $|A| > 1$. We show there is a $d \in \mathbb{F}_p^{\times}$ such that $d \cdot A$ contains a gap of size at least $2p/ |A| - 2 $.

Refinements of the inequalities between Neuman-Sandor, arithmetic, contra-harmonic and quadratic means [PDF]

arXiv, 2012
In this paper, we prove that the inequalities $\alpha [1/3 Q(a,b)+2/3 A(a,b)]+(1-\alpha)Q^{1/3}(a,b)A^{2/3}(a,b)0$ with $

Compact Subsets of the Glimm Space of a $C^*$-algebra [PDF]

arXiv, 2012
If $A$ is a $\sigma$-unital $C^*$-algebra and $a$ is a strictly positive element of $A$ then for every compact subset $K$ of the complete regularization $\mathrm{Glimm}(A)$ of $\mathrm{Prim}(A)$ there exists $\alpha > 0$ such that $K\subset \{G\in \mathrm{Glimm}(A) \mid \|a + G\|\geq \alpha\}$. This extends a 1974 result of J.

Inverses of triangular matrices and bipartite graphs [PDF]

arXiv, 2013
To a given nonsingular triangular matrix A with entries from a ring, we associate a weighted bipartite graph G(A) and give a combinatorial description of the inverse of A by employing paths in G(A). Under a certain condition, nonsingular triangular matrices A such that A and A^{-1} have the same zero-nonzero pattern are characterized.
