A CHARACTERIZATION OF THE n-SPHERE(x)

چکیده
1. Introduction. We give a set-theoretic characterization of the topologi-cal «-sphere. In so doing, we use some notions introduced by R. L. Wilder in his summer lectures of 1948 at the University of Michigan. Also an essential use is made' of modified forms of some results [l] of R. H. Bing.

متن کاملSolution Combustion Preparation Of Nano-Al2O3: Synthesis and Characterization
The aluminum oxide materials are widely used in ceramics, refractories and abrasives due to their hardness, chemical inertness, high melting point, non-volatility and resistance to oxidation and corrosion. The paper describes work done on synthesis of α-alumina by using the simple, non-expensive solution combustion method using glycine as fuel.Aluminum oxide (Al2O3) nanoparticles were synthesiz...
متن کاملCharacterization of $delta$-double derivations on rings and algebras
The main purpose of this article is to offer some characterizations of $delta$-double derivations on rings and algebras. To reach this goal, we prove the following theorem:Let $n > 1$ be an integer and let $mathcal{R}$ be an $n!$-torsion free ring with the identity element $1$. Suppose that there exist two additive mappings $d,delta:Rto R$ such that $$d(x^n) =Sigma^n_{j=1} x^{n-j}d(x)x^{j-1}+Si...
متن کاملSynthesis and characterization of Alumina (Al2O3) nanoparticles prepared by simple sol-gel method
Alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. This study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. Aluminium oxide (Al2O3) nanoparticles were synthesized by iron (III) nitrate 9-hydrate as precursor. Physicochemical properti...

متن کاملCharacterization of $(delta, varepsilon)$-double derivation on rings and algebras
This paper is an attempt to prove the following result:Let $n>1$ be an integer and let $mathcal{R}$ be a $n!$-torsion-free ring with the identity element. Suppose that $d, delta, varepsilon$ are additive mappings satisfyingbegin{equation}d(x^n) = sum^{n}_{j=1}x^{n-j}d(x)x^{j-1}+sum^{n-1}_{j=1}sum^{j}_{i=1}x^{n-1-j}Big(delta(x)x^{j-i}varepsilon(x)+varepsilon(x)x^{j-i}delta(x)Big)x^{i-1}quadend{e...
