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.

Recent advances in mathematics and theoretical computer science have enabled the synthesis of convex structures with fuzzy set theory, giving rise to novel approaches in fuzzy topology. This ...
