摘要

The role of open strings is investigated in the context of AdS3 flux vacua arising from type IIB orientifold reductions. On the one hand, contrary to expectations, the perturbative stability of certain recently found non-supersymmetric AdS3 flux vacua is shown to be robust under fluctuations of the open-string moduli. On the other hand, a wealth of new perturbatively stable AdS3 flux vacua appears as a consequence of the non-trivial dynamics of open-string moduli. We also comment on the issue of scale separation in these AdS3 flux vacua.
