 If is a ?2-grading of a simple Lie algebra, we explicitly describe a-module Spin0 () such that the exterior algebra of is the tensor square of this module times some power of 2. Let ${\mathfrak n}_n({\mathbb C})$ be the algebra of strictly upper-triangular $n\times n$ matrices and let ${\mathcal X}_2=\{u\in {\mathfrak n}_n({\mathbb C})\mid u^{2}=0\}$ be the subset of matrices of nilpotent order 2. In this paper, we classify all smooth affine spherical varieties up to coverings, central tori, and ${\mathbb C}^{\times}$-fibrations. It is also shown that on the nilmanifold $\Gamma\backslash (H^3\times H^3)$ the balanced condition is not stable under small deformations. We provide a direct computational proof of the known inclusion ${\cal H}({\bf R} \times {\bf R}) \subseteq {\cal H}({\bf R}^2),$ where ${\cal H}({\bf R} \times {\bf R})$ is the product Hardy space defined for example by R. 更多

 Frequency-Domain Bounds for Nonnegative, Unsharply Band-Limited Functions In this paper we give a further investigation of the method introduced by the author in [1, Frequency-domain bounds for nonnegative unsharply band-limited functions] for proving bounds for functions with nonnegative Fourier transforms. We present two-sided singular value estimates for a class of convolution-product operators related to time-frequency localization. This paper presents an expansion for radial tempered distributions on ${\bf R}^n$ in terms of smooth, radial analyzing and synthesizing functions with space-frequency localization properties similar to standard wavelets. The Balian-Low theorem (BLT) is a key result in time-frequency analysis, originally stated by Balian and, independently, by Low, as: If a Gabor system $\{e^{2\pi imbt} \, g(t-na)\}_{m,n \in \mbox{\bf Z}}$ 更多

 Free quotients and the first betti number of some hyperbolic manifolds In this note we present a very simple method of proving that some hyperbolic manifoldsM have finite sheeted covers with positive first Betti number. We then classify the reflections in the groupsW and the minimal number of them needed to generateW, using the diagrams. The least upper bound for the degrees of elements in a system of generators turns out to be independent of the number of vector variables.

 Relative standard deviations of the relative migration times of DNA segments were >amp;lt;3.6%. The molecular motional correlation times of two pairs of protons, H-1a/H-1b and H-2/H-3, in the bound state at T = 298 K were 11.7 and 9.46 ns respectively, while they were 27.7 and 35.2 ps in the free state. When the concentration of lanthanum nitrate was at 300 mg/L and 500 mg/L, and Q of the cultures reached 3.89 and 2.54 times of normal cultures, respectively. In this letter we investigate the three soliton interaction and their resonance phenomena of KP equation, and theoretically find that the maximum amplitude is 9 times of the initial interacting soliton for three same amplitude solitions. erythraeus in the 31-40 year-old protective forests were 3 and 3.75 times of those in the same-aged non-protective forests, respectively. 更多
