چکیده

In this paper we present a formula for the calculation of the integrals of the form ∫ S u∗Xuν(du), where S is the unit sphere in R , X is a positive semi-definite symmetric matrix, and ν is a surface measure generated by a Gaussian measure μ. The solution has the form trace(XZ), with the explicit procedure for the calculation of the matrix Z which does not depend on X. AMS subject classifications: 28A25, 58D20

Solvation Force in Hard Ellipsoid Molecular Liquids with Rod-Sphere and Rod- Surface Interactions

In previous work, one of us calculated the Solvation force of hard ellipsoid fluid with hard Gaussian overlap potential using hard needle wall interaction and non-linear equation proposed by Grimson- Rickyazen. In present work, using density functional theory and extended restricted orientation model, the solvation force of hard ellipsoid fluid in presence of more realistic rod- sphere and rod-...

Positive linear functionals without representing measures

For k even, let Pk denote the vector space of polynomials in 2 real variables of degree at most k. A linear functional L : Pk −→ R is positive if p ∈ Pk, p|R2 ≥ 0 =⇒ L(p) ≥ 0. Hilbert’s theorem on sums of squares (cf. [15]) implies that L : P4 −→ R is positive if and only if the moment matrix associated to L is positive semidefinite. In this note, using k = 6, we exhibit the first families of p...

Integration formulas for the conditional transform involving the first variation

In this paper, we show that the conditional transform with respect to the Gaussian process involving the first variation can be expressed in terms of the conditional transform without the first variation. We then use this result to obtain various integration formulas involving the conditional $diamond$-product and the first variation.

Giant Goos-Häenchen Shift of a Gaussian Beam Reflected from One-Dimensional Photonic Crystals Containing Left-Handed Lossy Metamaterials

We perform a theoretical investigation on the Goos-Häenchen shift (the lateral shift) in one-dimensional photonic crystals (1DPCs) containing left-handed (LH) metamaterials. The effect was studied by use of a Gaussian beam. We show that the giant lateral displacement is due to the localization of the electromagnetic wave which can be both positive and negative depending on the incidence angle o...
