Collapsing Dbranes in CalabiYau moduli space I
Abstract
We study the quantum volume of Dbranes wrapped around various cycles in CalabiYau manifolds, as the manifold's moduli are varied. In particular, we focus on the behaviour of these Dbranes near phase transitions between distinct low energy physical descriptions of the resulting string theory. Whereas previous studies have solely considered quantum volumes in the context of twocycles in perturbative string theory or Dbranes in the specific example of the quintic hypersurface, we work more generally and find qualitatively new features. On the mathematical side, as we briefly note, our work has some interesting implications for certain issues in arithmetic.
