Spherically Restricted Random Hyperbolic Diffusion
Philip Broadbridge, Alexander D. Kolesnik, Nikolai Leonenko +2
This paper investigates solutions of hyperbolic diffusion equations in with random initial conditions. The solutions are given as spatial-temporal random fields. The…
Non-particulate Klein-Gordon modes formed by inflation
Philip Broadbridge, Kathryn Deutscher
In a full solution for a scalar quantum field coupled to an accelerating isotropic universe, all constituent non-autonomous modes of elementary excitation cease to oscillate and be…
Fast Tensor Needlet Transforms for Tangent Vector Fields on the Sphere
Ming Li, Philip Broadbridge, Andriy Olenko +1
This paper constructs a semi-discrete tight frame of tensor needlets associated with a quadrature rule for tangent vector fields on the unit sphere of …
Random spherical hyperbolic diffusion
Phil Broadbridge, Alexander D. Kolesnik, Nikolai Leonenko +1
The paper starts by giving a motivation for this research and justifying the considered stochastic diffusion models for cosmic microwave background radiation studies. Then it deriv…
