Finiteness of N =4 super-Yang-Mills effective action in terms of dressed N =1 superfields
Igor Kondrashuk, Ivan Schmidt
We argue in favor of the independence on any scale, ultraviolet or infrared, in kernels of the effective action expressed in terms of dressed superfields for the case…
An accelerated closed universe
Sergio del Campo, Mauricio Cataldo, Francisco Pena
We study a model in which a closed universe with dust and quintessence matter components may look like an accelerated flat Friedmann-Robertson-Walker (FRW) universe at low redshift…
Curvature in causal BD-type inflationary cosmology
Francisco Pena, Mauricio Cataldo, Sergio del Campo
We study a closed model of the universe filled with viscous fluid and quintessence matter components in a Brans-Dicke type cosmological model. The dynamical equations imply that th…
On Magnetic solution to 2+1 Einstein--Maxwell gravity
M. Cataldo, J. Crisostomo, S. del Campo +1
The three--dimensional magnetic solution to the Einstein--Maxwell field equations have been considered by some authors. Several interpretations have been formulated for this magnet…
