Conformal Invariance for Non-Relativistic Field Theory

Momentum space Ward identities are derived for the amputated n-point Green’s functions in 3 + 1 dimensional non-relativistic conformal field theory. For n = 4 and 6 the implications for scattering amplitudes (i.e. on-shell amputated Green’s functions) are considered. Any scale invariant 2-to-2 scattering amplitude is also conformally invariant. However, conformal invariance imposes constraints ...

Action functionals for relativistic perfect fluids

Action functionals describing relativistic perfect fluids are presented. Two of these actions apply to fluids whose equations of state are specified by giving the fluid energy density as a function of particle number density and entropy per particle. Other actions apply to fluids whose equations of state are specified in terms of other choices of dependent and independent fluid variables. Parti...

Control of Turbulent Flows

It is useful for many industrial applications to be able to control turbulence in uid ows, either to reduce it or, in some cases, to increase it. Active or passive control procedures are of interest. The problems that we face here are considerable and encompass those related to the control of complex nonlinear systems and those related to the direct numerical simulation of turbulent ows. Our ai...

Conformal Mappings in Relativistic Astrophysics

We describe the use of conformalmappings as amathematicalmechanism to obtain exact solutions of the Einstein field equations in general relativity. The behaviour of the spacetime geometry quantities is given under a conformal transformation, and the Einstein field equations are exhibited for a perfect fluid distribution matter configuration. The field equations are simplified and then exact sta...

Turbulent Flows: General Properties

Turbulence is ubiquitous in natural fluids: atmosphere, ocean, lakes, rivers, Earth’s interior, planetary atmospheres and their convective interiors, stars, and space gases (neutral and ionized). From a mathematical perspective, its essential behaviors arise because the equations of fluid dynamics are a nonlinear partial differential equation (PDE) system. From an accompanying physical perspect...
