In mathematics and theoretical physics, a quasi-sphere is a generalization of the hypersphere and the hyperplane to the context of a pseudo-Euclidean space. It may be described as the set of points for which the quadratic form for the space applied to the displacement vector from a centre point is a constant … See more This article uses the following notation and terminology: • A pseudo-Euclidean vector space, denoted R , is a real vector space with a nondegenerate quadratic form with signature (s, … See more Referring to the quadratic form applied to the displacement vector of a point on the quasi-sphere from the centre (i.e. Q(x − p)) as the radial scalar square, in any pseudo-Euclidean space the quasi-spheres may be separated into three disjoint sets: those with positive radial … See more A quasi-sphere is a submanifold of a pseudo-Euclidean space E consisting of the points u for which the displacement vector x = u − o from a reference point o satisfies the equation See more Centre and radial scalar square The centre of a quasi-sphere is a point that has equal scalar square from every point of the quasi-sphere, the point at which the pencil of … See more • Anti-de Sitter space • de Sitter space • Hyperboloid § Relation to the sphere See more WebMany translated example sentences containing "quasi-spherical" – French-English dictionary and search engine for French translations.

WebJan 28, 2024 · 1. To put it simply: Plasma is described as a quasi-neutral gas consisting of ions and electrons. You know that electrons are negatively charged and ions (typically ionised by losing an electron) are positive. To sustain a stable plasma, it must be subject to an electric field (lets say between an alternating bias of electrodes) and at a gas ... WebJun 6, 2016 · A new and consistent model is developed to describe the growth of gold nanoparticles (Au NPs) via citrate reduction of auric acid (HAuCl4) by carefully assessing the temporal evolution of the NP sizes and surface charges by means of dynamic light scattering (DLS) and zeta-potential measurements.
