Spherical subcategories in algebraic geometry [PDF]
, 2016 We study objects in triangulated categories which have a two-dimensional graded endomorphism algebra. Given such an object, we show that there is a unique maximal triangulated subcategory, in which the object is spherical.

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 geometry and integrable systems [PDF]
, 2012 We prove that the cosine law for spherical triangles and spherical tetrahedra defines integrable systems, both in the sense of multidimensional consistency and in the sense of dynamical systems.Comment: 15 pages, 5 ...

Proceedings of the Edinburgh Mathematical Society, 1883 The object of this paper is to bring together the principal properties of figures described on the surface of the sphere that can be established without the use of Solid Geometry or of Trigonometry. The following properties of the spherical surface, which correspond to the definitions and axioms in Plane Geometry, are assumed. They may be considered

Geochemistry, Geophysics, Geosystems, 2022 Many of the factors expected to control the dynamics and evolution of Earth's subduction zones are under‐explored in an Earth‐like spherical geometry. Here, we simulate multi‐material free‐subduction of a complex rheology slab in a 3‐D spherical shell ...

Detecting Cocircular Subsets of a Spherical Set of Points
Journal of Imaging, 2022 Given a spherical set of points, we consider the detection of cocircular subsets of the data. We distinguish great circles from small circles, and develop algorithms for detecting cocircularities of both types.

Cylindrical and spherical modified Gardner solitons in five component dusty plasmas
AIP Advances, 2023 The propagation of nonplanar (cylindrical or spherical) Gardner solitons (GSs) in a plasma system containing nonthermally distributed heavy ions, light ions, q nonextensive distributed electrons, and arbitrarily charged dusts is studied theoretically and

Compressible MHD in Spherical Geometry [PDF]
International Astronomical Union Colloquium, 1991 AbstractThe generation of magnetic field by a conducting, compressible fluid inside a spherical shell is studied by direct numerical simulations. A pseudo-spectral method is used in order to resolve accurately all the scales present in the problem. The range of parameters considered is the following: a unit Prandtl number, Rayleigh numbers up to 100 ...

Statistical Models on Spherical Geometries [PDF]
Physical Review Letters, 1995 We use a one-dimensional random walk on $D$-dimensional hyper-spheres to determine the critical behavior of statistical systems in hyper-spherical geometries. First, we demonstrate the properties of such a walk by studying the phase diagram of a percolation problem.
