T-duality Covariance of SuperD-branes [PDF]

open access: yes, 2000
T-duality realized on SuperD-brane effective actions probing in constant $G_{mn}$ and $b_{mn}$ backgrounds is studied from a pure world volume point of view.

Effects of discrete energy and helicity conservation in numerical simulations of helical turbulence

open access: yes, 2017
Helicity is the scalar product between velocity and vorticity and, just like energy, its integral is an in-viscid invariant of the three-dimensional incompressible Navier-Stokes equations.

Superpotentials in IIA compactifications with general fluxes [PDF]

open access: yes, 2004
We derive the effective N=1, D=4 supergravity for the seven main moduli of type IIA orientifolds with D6 branes, compactified on T^6/(Z_2xZ_2) in the presence of general fluxes.

SL(N+1,R) Toda Solitons in Supergravities

open access: yes, 1996
We construct $(D-3)$-brane and instanton solutions using $N \le 10-D$ one-form field strengths in $D$ dimensions, and show that the equations of motion can be cast into the form of the $SL(N+1,R)$ Toda equations.

Dualisation of Dualities, I [PDF]

open access: yes, 1997
We analyse the global (rigid) symmetries that are realised on the bosonic fields of the various supergravity actions obtained from eleven-dimensional supergravity by toroidal compactification followed by the dualisation of some subset of fields.

Grad's Moment Method for a Low-Density Granular Gas. Navier-Stokes Transport Coefficients

open access: yes, 2012
The Navier-Stokes transport coefficients for a granular gas of smooth inelastic hard disks or spheres are determined from the inelastic Boltzmann equation by means of Grad's moment method. The shear viscosity $\eta$, the thermal conductivity $\kappa$ and

Exact solutions in multidimensional gravity with antisymmetric forms

open access: yes, 2005
This topical review deals with a multidimensional gravitational model containing dilatonic scalar fields and antisymmetric forms. The manifold is chosen in the form M = M_0 x M_1 x ...x M_n, where M_i are Einstein spaces (i >0).

Inverse dualisation and non-local dualities between Einstein gravity and supergravities [PDF]

open access: yes, 2001
We investigate non-local dualities between suitably compactified higher-dimensional Einstein gravity and supergravities which can be revealed if one reinterprets the dualised Kaluza-Klein two-forms in $D>4$ as antisymmetric forms belonging to ...

Black-brane solution for A_3 algebra [PDF]

open access: yes, 2002
Black p-brane solutions for a wide class of intersection rules and Ricci-flat ``internal'' spaces are considered. They are defined up to moduli functions H_s obeying non-linear differential equations with certain boundary conditions imposed.
