Algebraic Elements in Group Rings
In this brief note, we study algebraic elements in the complex group algebra C[G]. Specifically, suppose £ e C[G] satisfies /(£) = 0 for some nonzero polynomial f(x) e C[x]. Then we show that a certain fairly natural function of the coefficients of Z is bounded in terms of the complex roots of f(x). For G finite, this is a recent observation of [HLP], Thus the main thrust here concerns infinite...
متن کاملPlasma Variations in Saturn‘s Magnetosphere from the Main Rings To
1 University of Virginia, Charlottesville, VA 4 2 Laboratory for Atmospheric and Space Science, Boulder, CO 5 6 Abstract 7 With the discovery of an oxygen atmosphere over Saturn‘s main rings by Cassini (Tokar et 8 al., 2005; Johnson et al. 2006), as well a strong, but variable source from the plumes emanating 9 from Saturn‘s moon Enceladus (Porco et al., 2005; Smith et al., 2010) our picture of...
متن کاملAntisymmetric Elements in Group Rings Ii
Let R be a commutative ring, G a group and RG its group ring. Let φ : RG → RG denote the R-linear extension of an involution φ defined on G. An element x in RG is said to be φantisymmetric if φ(x) = −x. A characterization is given of when the φ-antisymmetric elements of RG commute. This is a completion of earlier work. keywords: Involution; group ring; antisymmetric elements. keywords: 2000 Mat...
متن کاملApplication of AIM parameters at ring critical points for estimation of pi-electron delocalization in six-membered aromatic and quasi-aromatic rings.
The AIM parameters at the ring critical point (the electron density and its Laplacian, the total electron energy density and both its components, potential and kinetic electron energy densities), have been intercorrelated with aromaticity indices: the geometry-based HOMA and the magnetism-based NICS, NICS(1), and NICS(1)(zz). A set of 33 phenylic rings having possibly a diversified aromatic cha...
