New Discrete Basis for Nuclear Structure Studies [PDF]
, 1998 A complete discrete set of spherical single-particle wave functions for studies of weakly-bound many-body systems is proposed. The new basis is obtained by means of a local-scale point transformation of the spherical harmonic oscillator wave functions ...

Optimal Bounds for Neuman Means in Terms of Harmonic and Contraharmonic Means
Journal of Applied Mathematics, 2013 For a,b>0 with a≠b, the Schwab-Borchardt mean SB(a,b) is defined as SB(a,b)={b2-a2/cos-1(a/b) if ab. In this paper, we find the greatest values of α1 and α2 and the least values of β1 and β2 in [0,1/2] such that H ...

Highly degenerate harmonic mean curvature flow [PDF]
Calculus of Variations and Partial Differential Equations, 2008 We study the evolution of a weakly convex surface $ _0$ in $\R^3$ with flat sides by the Harmonic Mean Curvature flow. We establish the short time existence as well as the optimal regularity of the surface and we show that the boundaries of the flat sides evolve by the curve shortening flow.

Abstract and Applied Analysis, 2012 We present the best possible lower and upper bounds for the Neuman-Sándor mean in terms of the convex combinations of either the harmonic and quadratic means or the geometric and quadratic means or the harmonic and contraharmonic means.

An inequality of W. L. Wang and P. F. Wang
International Journal of Mathematics and Mathematical Sciences, 1990 In this note we present a proof of the inequality Hn/H′n≤Gn/G′n where Hn and Gn (resp. H′n and G′n) denote the weighted harmonic and geometric means of x1,…,xn (resp. 1−x1,…,1−xn) with xi∈(0,1/2], i=1,…,n.

Harmonic Loads Classification by Means of Currents’ Physical Components
Energies, 2019 Electric load identification and classification for smart grid environment can improve the power service for both consumers and producers. The main concept of electric load identification and classification is to disaggregate various loads and categorize

On Submanifolds with Harmonic Mean Curvature [PDF]
Proceedings of the American Mathematical Society, 1995 The classification of curves in E m {E^m} with harmonic mean curvature vector field in the normal bundle is obtained and then it is used to obtain some applications.

Inequalities between Power Means and Convex Combinations of the Harmonic and Logarithmic Means
Journal of Applied Mathematics, 2012 We prove that αH(a,b)+(1−α)L(a,b)>M(1−4α)/3(a,b) for α∈(0,1) and all a,b>0 with a≠b if and only if α∈[1/4,1) and αH(a,b)+(1−α)L(a,b)

Harmonic analysis and mean field theory [PDF]
Journal of High Energy Physics, 2019 Abstract We review some aspects of harmonic analysis for the Euclidean conformal group, including conformally-invariant pairings, the Plancherel measure, and the shadow transform. We introduce two efficient methods for computing these quantities: one based on weight-shifting operators, and another based on Fourier space.

Harmonic entanglement with second-order non-linearity [PDF]
, 2005 We investigate the second-order non-linear interaction as a means to generate entanglement between fields of differing wavelengths. And show that perfect entanglement can, in principle, be produced between the fundamental and second harmonic fields in ...
