Vacuum Selection from Cosmology on Networks of String Vacua.
Large sets of Calabi-Yau manifolds, relevant for constructing 4d effective field theories from string theory, form a connected network of geometries, via topological transitions between them that correspond to zero-energy deformations (motion in moduli space). I will discuss how this structure may determine leading-order vacuum transitions, and how the network structure can therefore provide a notion of vacuum selection in the string landscape.
