The Surface Expression of Deep Columnar Flows
Geochemistry, Geophysics, Geosystems, 2020 Studies of the Earth's secular variation have blossomed in recent decades, due to the availability of brand‐new satellite data. In particular, flow inversions at the core surface that incorporate the effects of rapid rotation a priori have been able to ...

Geometric Properties of Planar and Spherical Interception Curves
Axioms, 2023 In this paper, some geometric properties of the plane interception curve defined by a nonlinear ordinary differential equation are discussed. Its parametric representation is used to find the limits of some triangle elements associated with the curve ...

Spherical isotropy representations [PDF]
Publications Mathématiques de l'IHÉS, 1985 An old question of P. A. Smith considers a finite group G acting smoothly on a closed homotopy sphere \(\Sigma\) with \(\Sigma^ G\) consisting of precisely two points and asks whether the representations of G on the tangent spaces at the two fixed points are the same. This would be true, obviously, for a linear action on a sphere.

Spherical harmonic representation of the observed directional wave front in the time domain [PDF]
JASA Express Letters, 2022 Sound field reproduction algorithms require loudspeaker directivity, which is usually measured at discrete frequencies. A time domain model of loudspeaker directivity benefits broadband applications. This Letter proposes the concept of a directional wave

Discrete element modeling of non-spherical particles using a spherical shape
REM: International Engineering Journal, 2020 Real non-spherical particles can be modeled using the Discrete Element Method (DEM) with sphere clusters, superquadrics, or polyhedral particles. However, in applications involving a considerable number of particles, the analysis can become impracticable.

The tempered spectrum of a real spherical space [PDF]
, 2017 Let G/H be a unimodular real spherical space which is either absolutely spherical or wave-front. It is shown that every tempered representation of G/H embeds into a relative discrete series of a boundary degeneration of G/H. If in addition G/H is of wave-

Spherical orbits and representations of Uε(g) [PDF]
Transformation Groups, 2005 Let Ue(g) be the simply connected quantized enveloping algebra at roots of one associated to a finite dimensional complex simple Lie algebra g. The De Concini-Kac-Procesi conjecture on the dimension of the irreducible representations of Ue(g) is proved for the representations corresponding to the spherical conjugacy classes of the simply connected ...
