We present the idea of asymptotic grand unification, where the gauge couplings run to a unique fixed point in the ultraviolet, thanks to the presence of a compact extra dimension and to a specific choice group structure and multiplet content. We introduce a minimal model based on a SU(5) gauge theory but also discuss SO(10) and other generalisations, giving also few results on the expected...
We propose to discuss the modular flavor model and the stabilization of single modulus field in the Jordan frame supergravity with non-minimal scalar-curvature coupling of the form $\Phi(\tau,\bar{\tau})R$. Modular invariance and positivity of the scale factor constrain stringently the form of the frame function, consequently the Kahler potential. We discuss some general properties of scalar...
