Abstract:
We discuss the symmetries of vacuum configurations in stabilized five-dimensional brane-world models and their relation to the properties of solutions of the corresponding equations of motion. With the example of a model admitting the four-dimensional de Sitter metric on the branes, we show that the existence of such symmetries in some cases leads to a decrease in the number of fundamental parameters to be fine tuned.
Keywords:
extra dimension, brane-world model, cosmological constant.
