Instanton amplitudes in open-closed topological string theory
C. I. Lazaroiu
I use the universal instanton formalism to discuss quantum effects in the open-closed topological string theory of a Calabi-Yau A-model, in the presence of a multiply-wrapped `Floe…
On the structure of open-closed topological field theory in two dimensions
C. I. Lazaroiu
I discuss the general formalism of two-dimensional topological field theories defined on open-closed oriented Riemann surfaces, starting from an extension of Segal's geometric axio…
Collapsing D-branes in one-parameter models and small/large radius duality
C. I. Lazaroiu
We finalize the study of collapsing D-branes in one-parameter models by completing the analysis of the associated hypergeometric hierarchy. This brings further evidence that the ph…
Collapsing D-Branes in Calabi-Yau Moduli Space: I
Brian R. Greene, C. I. Lazaroiu
We study the quantum volume of D-branes wrapped around various cycles in Calabi-Yau manifolds, as the manifold's moduli are varied. In particular, we focus on the behaviour of thes…
