We derive the explicit form, and discuss some properties of the moduli dependent effective potential arising from M-theory compactified on M 4 × X × S 1 /Z 2 , when one of the boundaries supports a strongly interacting gauge sector and induces gaugino condensation. We discuss the relation between the explicit gaugino condensate and effective superpotential formulations and find interesting diff...

residue number system (rns) is a carry-free and non-weighed integer system. in this paper an improved three-moduli set  in reverse converter based on crt algorithm is proposed. crt algorithm can perform a better delay and hardware implementation in modules via other algorithms. this moduli is based on p that covers a wide range on modules and supports the whole range of its modules in dynamic r...

By studying an effective action description of the coupling of charged gauge fields in N = 2 SU(n) supersymmetric Yang-Mills theories, we can describe regions of moduli space where one or more of these fields becomes unphysical. We discuss subtleties in the structure of the moduli space for SU(3). e-mail address: [email protected] e-mail address: [email protected] 1

We extend the KKLT [1] approach to moduli stabilization by including the dilaton and the complex structure moduli into the effective supergravity theory. Decoupling of the dilaton is neither always possible nor necessary for the existence of stable minima with zero (or positive) cosmological constant. The pattern of supersymmetry breaking can be much richer than in the decoupling scenario of KKLT.

∗∗ Local and global properties of the moduli space of Calabi–Yau type compactifications determine the low energy parameters of the string effective action. We show that the moduli space geometry is entirely encoded in the Picard–Fuchs equations for the periods of the Calabi– Yau H–cohomology. ∗ Supported in part by DOE grants DE-AC0381-ER500050, DOE-AT03-88ER40384, task E and by MURST.

We discuss the low-energy effective string theory when moduli of the compactified manifold are present. Assuming a nontrivial coupling of the moduli to the Maxwell tensor, we find a class of regular black hole solutions. Both the thermodynamical and the geometrical structure of these solutions are discussed. 1
