Abstract: | Using the 5-dimensional supergravity as an example, the problem of gauge dependence of the effective action (EA) of multidimensional SUGRA's is discussed. The standard and the Vikovisky-De Witt EA's are computed up to the terms linear in curvature for d=5, N=2, 4, 6, 8 SUGRA's on the R4,×S1 background, where R4, is a 4-dimensional curved space, and S1 a 1-dimensional sphere. The standard EA obtained in d=5, N= 2 gauge SUGRA on the R40×S1, where R40 is a flat 4-dimensional space, depends on three gauge parameters. The gauge-invariant Vilkovsky-De Witt EA is computed for a d=5 SUGRA with broken symmetry on the r40×S1 background, where R40 is a 4-dimensional space with nonzero temperature.Translated from Izvestiya Vyssihkh Uchebnykh Zavedenii, Fizika, No. 5, pp. 53–59, May, 1989.I am grateful to I.
