On the second spectrum and the second classical Zariski topology of a module

Journal of Algebra and Its Applications, 2015
Let R be an associative ring with identity and Specs(M) denote the set of all second submodules of a right R-module M. In this paper, we investigate some interrelations between algebraic properties of a module M and topological properties of the second classical Zariski topology on Specs(M). We prove that a right R-module M has only a finite number of

The Zariski Topology on the Second Spectrum of a Module

Algebra Colloquium, 2014
Let R be a commutative ring and M be an R-module. The second spectrum Spec s(M) of M is the collection of all second submodules of M. We topologize Spec s(M) with Zariski topology, which is analogous to that for Spec (M), and investigate this topological space.

Second-stage spectrum of corona of two graphs

Discrete Mathematics, Algorithms and Applications, 2021
The derived graph of a simple graph [Formula: see text], denoted by [Formula: see text], is the graph having the same vertex set as [Formula: see text], in which two vertices are adjacent if and only if their distance in [Formula: see text] is two. The spectrum of derived graph of [Formula: see text] is called the second-stage spectrum of [Formula ...

The Second Spark Spectrum of Lead

Nature, 1929
THE second spark spectrum of lead was recently analysed by K. R. Rao and ourselves; and a preliminary report of the series regularities discovered was published in a paper (Ind. J. Phy., vol. 2, pt. 4, pp. 468-476.) We have since become aware of a similar publication by Smith (Proc. N. A. S., vol. 14, pp. 878-880; 1928).

EXTENDED-SPECTRUM (SECOND-AND THIRD-GENERATION) CEPHALOSPORINS

Obstetrics and Gynecology Clinics of North America, 1992
The extended-spectrum cephalosporins provide better activity against gram-negative bacilli and anaerobes than first-generation agents. Cefoxitin and cefotetan (second-generation) and ceftriaxone (third-generation) have excellent activity against B. fragilis and are useful in the treatment of postoperative infections and pelvic inflammatory disease.

The second spectrum of silicon

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1961
Abstract New observations of the spectrum Si II from λ 700 to λ 9500 are described, 300 lines being listed in addition to those previously assigned to this spectrum. The analysis includes details of the perturbations of the 3s2nx2 X series up to x = g.

The second spectrum of germanium

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1963
Abstract The spectrum of Ge II has been remeasured from 600 to 10000 Å. The analysis has led to the calculation of m any very accurate Ritz standards in the vacuum region. The doublet series are less perturbed than in Si II but auto-ionization is more severe.
