The Wheeler-De Witt equation of type IIB quantum string cosmology compactified with constant internal H-fluxes on a 6-torus, whose volume modulus is frozen, is solved under the WKB approximation. The spontaneous symmetry breaking of the S-duality group by H-fluxes is also examined.

Time and a Temporally Statistical Quantum Geometrodynamics

This paper is an exposition of the author's recent work on modeling M-theory vacua and quantum mechanical observers in the framework of a temporally statistical description of quantum

Compactification of Type Iib Theory with Fluxes and Axion-Dilaton String Cosmology

Compactification of type IIB theory on torus, in the presence of fluxes, is considered. The reduced effective action is expressed in manifestly S-duality invariant form. Cosmological solutions of the

A Schematic Model of Gauged S-Duality Spontaneous Breakdown

We present a schematic model of the \hat{sl(2,R})} Kugo-Ojima physical state condition of gauged S-duality using modular forms of the Ramanujan \Delta function type. The properties of the solutions



TASI Lectures on the cosmological constant

The energy density of the vacuum, Lambda, is at least 60 orders of magnitude smaller than several known contributions to it. Approaches to this problem are tightly constrained by data ranging from


The axion–dilaton string effective action is expressed in Einstein frame metric in a manifestly S-duality invariant form. It is shown that the moduli can be redefined to describe surface of a

Strong-Weak Coupling Duality in Four-Dimensional String Theory

We present several pieces of evidence for strong–weak coupling duality symmetry in the heterotic string theory, compactified on a six-dimensional torus. They include symmetry of the (1) low energy

Quantum Background Independence In String Theory

Not only in physical string theories, but also in some highly simplified situations, background independence has been difficult to understand. It is argued that the ``holomorphic anomaly'' of
