We study in detail some aspects of duality between type IIB and M-theory. We focus on the duality between type IIB string theory on K3 x T-2/Z(2) orientifold and M-theory on K3 x K3, in the F-theory limit. We give the explicit map between the fields and in particular between the moduli of compactification, studying their behavior under the F-theory limit. Turning on fluxes generates a potential for the moduli both in type IIB and in M-theory. We verify that the type IIB analysis gives the same results of the F-theory analysis. In particular we check that the two potentials match.

Abstract
We study in detail some aspects of duality between type IIB and M-theory. We focus on the duality between type IIB string theory on K3 x T-2/Z(2) orientifold and M-theory on K3 x K3, in the F-theory limit. We give the explicit map between the fields and in particular between the moduli of compactification, studying their behavior under the F-theory limit. Turning on fluxes generates a potential for the moduli both in type IIB and in M-theory. We verify that the type IIB analysis gives the same results of the F-theory analysis. In particular we check that the two potentials match.File in questo prodotto:
