Open+Questions+&+Discussions

During the introductions and overview talks a number of open questions / big issues were mentioned. Those are collected here as keywords - treat them as a "to do" list for the workshop...

Mathematical issues in model building:
 * sheaves for heterotic strings
 * G4-form flux in F-theory
 * biased landscape counting
 * M5-brane instantons intrinsically
 * geometric transitions in compact models

Moduli stabilization issues:
 * dynamical stringy realization of gauge mediation without any prior fixing of some moduli by hand
 * dynamical realization of large extra dimensions (LVS) without light scalars
 * dynamical realization of inflation
 * stabilization of IIB/F-theory & other moduli taking mutual conditions for fluxes/branes/instantons into account
 * universal predictions for certain classes of string models
