Interpolative Fusions

School
MATHEMATICS

The new notion of interpolative fusions provides a unified framework for studying many examples of "generic constructions" in model theory. Some, like structures with generic predicates, or algebraically closed fields with several independent valuations, are explicitly interpolative fusions, while others, like structures with generic automorphisms, or fields with generic operators, are bi-interpretable with interpolative fusions. The idea is to take two expansions T and T' of a common reduct theory and study models of their union such that the T and T' structures interact "randomly" up to constrains imposed by the common reduct. If T and T' a ...
