A new way how to calculate the off-shell renormalization functions within the R 2-gravity has been proposed. The one-loop renormaliza-tion group equations in the approach suggested have been constructed. The behaviour of effective potential for an massless scalar field interacting with the quantum gravitational field has been analyzed in this approach.

We show that the D=5 dilaton-axion gravity compactified on a 2-torus possesses the SL(4,R)/SO(4) matrix formulation. It is used for construction of the SO(2,2)-invariant BPS solution depended on the one harmonic function. 1 [email protected] 2 [email protected]

A massive gauge invariant formulation for scalar (φ) and antisymmetric (C mnp) fields with a topological coupling, which provides a mass for the axion field, is considered. The dual and local equivalence with the non-gauge invariant proposal is established, but on manifolds with non-trivial topological structure both formulations are not globally equivalent.
