Scientific paper

A mechanism of the cosmological constant vanishing in gauged N = 4 supergravity on the background Mp = Tp×R4-p at finite temperature is analysed. Here Tp, R4-p are the p-dimensional torus and the flat space, respectively, p = 1,...,4. It is shown that this mechanism results from the one-loop Casimir effect. Some cosmological scenarios and the possibility of extending these results to gauged N = 8 supergravity are discussed.
