Description

Part of the moduli space of type II string compactifications on Calabi-Yau threefolds is characterized by the variation of Hodge structure of the complex structure moduli space of the Calabi-Yau threefold.
In this talk, we will discuss subspaces of the complex structure moduli space, which are realized in terms of a closed variation of sub-Hodge structures. Physically, such sub-Hodge structures give rise to Minkowski-vacua of the associated gauged N=2 supergravity theory. We will illustrate these concepts with concrete examples of 2-parameter moduli spaces of Calabi-Yau threefolds.
