In the present paper, the nonlinear equations describing all the nonsingular pencils of metrics of constant Riemannian curvature are derived and the integrability of these nonlinear equations by the method of inverse scattering problem is proved. These results were announced in our previous paper [1]. For the flat pencils of metrics the corresponding statements and proofs were presented in the ...
In this paper, we study vector-valued elliptic operators of the form $${\mathcal {L}}f:=\mathrm {div}(Q\nabla f)-F\cdot \nabla f+\mathrm {div}(Cf)-Vf$$ acting on functions $$f:\mathbb {R}^d\rightarrow \mathbb {R}^m$$ and involving coupling at zero first order terms. We prove that {L}}$$ admits realizations in $$L^p(\mathbb {R}^d,\mathbb {R}^m)$$ , for $$1<p<\infty $$ generate analytic strongly ...
In image quality assessment, preference for various image processing algorithms or treatments is often determined using paired comparisons. In this experimental design, pairs of images processed by different algorithms or “treatments” are presented to a judge. The preferred treatment is selected and a tally is kept of the number of times each treatment is preferred to another. It is possible to...
Consider an N×n random matrix Yn = (Y n ij ) where the entries are given by Y ij = σij (n) √ n X ij , the X n ij being independent and identically distributed, centered with unit variance and satisfying some mild moment assumption. Consider now a deterministic N × n matrix An whose columns and rows are uniformly bounded in the Euclidean norm. Let n = Yn +An. We prove in this article that there ...
N-Acyloctahydropyrido[3,2,1-ij][1,6]naphthyridines were synthesized as derivatives of matrine-type alkaloids, and the structure-activity relations were examined by the acetic acid-induced abdominal contraction test. The antinociceptive potencies of N-acyloctahydropyrido[3,2,1-ij][1,6]naphthyridines were significantly lower than those of (+)-matrine. The antinociceptive effects of N-benzyloctahy...
Photon propagation in a gas of N atoms is studied using an effective Hamiltonian describing photon-mediated atomic dipolar interactions. The density P(Gamma) of photon escape rates is determined from the spectrum of the NxN random matrix Gamma_{ij}=sin(x_{ij})/x_{ij}, where x_{ij} is the dimensionless random distance between any two atoms. Varying disorder and system size, a scaling behavior is...
The cross section, the deuteron vector A(d)(y) and tensor analyzing powers A(ij), the polarization transfer coefficients K(y('))(ij), and the induced polarization P(y(')) were measured for the dp elastic scattering at 270 MeV. The cross section and A(d)(y) are well reproduced by Faddeev calculations with modern data-equivalent nucleon-nucleon forces plus the Tucson-Melbourne three-nucleon force...
In this document we provide a couple of exercises that help understand the basic concepts of game theory, including pure and mixed strategies, zero sum and non-zero sum games, and saddle-point and Nash solutions. The definition for concepts and the ideas for these exercises were taken in part from [1, 2]. Before we start, let us introduce some notation. We are going to assume that we have only ...
