We prove a main gap theorem for locally saturated submodels of a homogeneous structure. We also study the number of locally saturated models, which are not elementarily embeddable into each other.
All the homogeneous structures on the generalized Heisenberg group $H(p, 1)$ are found, obtaining a one-parameter family of quasi-Sasakian homogeneous structures on ...
