Gravitational Collapse in Higher Dimensional Husain Space-Time

We investigate exact solution in higher dimensional Husain model for a null fluid source with pressure p and density ρ are related by the following relations (i) p = kρ, (ii) p = kρ− B(v) ρα (variable modified Chaplygin) and (iii) p = kρ (polytropic). We have studied the nature of singularity in gravitational collapse for the above equations of state and also for different choices of the of the...

Higher order variational space-time approximation of wave propagation

The accurate and reliable numerical approximation of wave propagation is of fundamental importance to the simulation of acoustic, electromagnetic and elastic phenomena. In mechanical engineering, advanced composites such as carbon fibre reinforced polymer have become one of the most promising materials to build light-weight structures for several fields of application, for instance in aerospace...

Weak Alfvén-wave turbulence revisited.

Weak Alfvénic turbulence in a periodic domain is considered as a mixed state of Alfvén waves interacting with the two-dimensional (2D) condensate. Unlike in standard treatments, no spectral continuity between the two is assumed, and, indeed, none is found. If the 2D modes are not directly forced, k(-2) and k(-1) spectra are found for the Alfvén waves and the 2D modes, respectively, with the lat...

Chiral Alfvén Wave in Anomalous Hydrodynamics.

We study the hydrodynamic regime of chiral plasmas at high temperature. We find a new type of gapless collective excitation induced by chiral effects in an external magnetic field. This is a transverse wave, and it is present even in incompressible fluids, unlike the chiral magnetic and chiral vortical waves. The velocity is proportional to the coefficient of the gravitational anomaly. We brief...

Space-Time and Higher Dimensional Modeling for Animation

There are limitations to the current BRep based “model then animate” paradigm when animating time-dependent (dynamic) objects. This paper describes an approach to modeling dynamic objects directly in space-time or even higher dimensional space. The use of the function representation (FRep) is proposed due to the ease with which it handles higher dimensions. After creating a multidimensional FRe...
