Vacuum Stability in Heterotic M-Theory
Evgeny I. Buchbinder, Burt A. Ovrut
The problem of the stabilization of moduli is discussed within the context of compactified strongly coupled heterotic string theory. It is shown that all geometric, vector bundle a…
Global Fluctuation Spectra in Big Crunch/Big Bang String Vacua
Ben Craps, Burt A. Ovrut
We study Big Crunch/Big Bang cosmologies that correspond to exact world-sheet superconformal field theories of type II strings. The string theory spacetime contains a Big Crunch an…
The Moduli of Reducible Vector Bundles
Yang-Hui He, Burt A. Ovrut, Rene Reinbacher
A procedure for computing the dimensions of the moduli spaces of reducible, holomorphic vector bundles on elliptically fibered Calabi-Yau threefolds X is presented. This procedure…
Invariant Homology on Standard Model Manifolds
Burt A. Ovrut, Tony Pantev, Rene Reinbacher
Torus-fibered Calabi-Yau threefolds Z, with base dP_9 and fundamental group pi_1(Z)=Z_2 X Z_2, are reviewed. It is shown that Z=X/(Z_2 X Z_2), where X=B X_{P_1} B' are elliptically…
