Introduction, cont’d So far I’ve just reviewed various heteroticcompactifications. In this talk, I’m interested in the possible deformations, the `moduli,’ of such heteroticcompactifications. Broadly speaking, the moduli are: * metric moduli * bundle moduli and because of conditions such as F ij = 0 = F ıj , these can be intertangled.
Introduction, cont’d In Calabi-Yau compactifications, these moduli have been identified with complex, Kahler, bundle moduli for many years (though updated recently, and worldsheet description missing). In non-Kahler heteroticcompactifications, moduli have been a mystery. Today, I’ll present an expression for moduli ofheterotic non-Kahler compactifications (which will also give a worldsheet description of recent updates to Calabi-Yau story).
