De-Sitter and double asymmetric brane worlds
Rommel Guerrero, R. Omar Rodriguez, Rafael Torrealba
Asymmetric brane worlds with dS expansion and static double kink topology are obtained from a recently proposed method and their properties are analyzed. These domain walls interpo…

Membrane's Discrete Spectrum and BRST Residual Symmetry in the Conformal Light Cone Gauge
R. Torrealba
In this work we present a proof of the discreteness of the spectrum for bosonic membrane, in a flat minkowski space. This may be useful to show the quantum mechanical consistence o…
