Supersymmetry and stationary solutions in dilaton-axion gravity
Gravity is fixed charged Taub - the NUT steel pipe concrete the construction
2014/12/23
New stationary solutions of four-dimensional dilaton-axion gravity are presented, which correspond to the charged Taub-NUT and Israel-Wilson-Perjés (IWP) solutions of Einstein-Maxwell theory. The char...
Solving the stationary Liouville equation via a boundary element method
Statistical energy analysis high-frequency asymptotics Liouville equation boundary element method
2012/2/29
Intensity distributions of linear wave fields are, in the high frequency limit, often approximated in terms of flow or transport equations in phase space. Common techniques for solving the flow equati...

2011/7/21
Starting from a classical picture of shear viscosity we construct a stationary velocity gradient in a microscopic parton cascade. Employing the Navier-Stokes ansatz we extract the shear viscosity coef...

We present a summary of current knowledge about the AGT relations for conformal blocks with additional insertion of the simplest degenerate operator, and a special choice of the corresponding interme...
Stationary point approach to the phase transition of the classical XY chain with power law interactions
Stationary point power law interactions
2010/11/25
The stationary points of the Hamiltonian H of the classical XY chain with power law pair
interactions (i. e., decaying like r− with the distance) are analyzed. For a class of “spinwave-type”st...

2010/12/20
We present the first stationary, axisymmetric neutron star models with meridional circulation in general relativity. For that purpose, we developed GRNS, a new code based on a fixed point iteration.
