Abstract:
Rank values for various families of order
theories are described as depending on the languages under consideration; a
description of
ee-total transcendence in terms of these languages is also given.
Approximations of order theories are studied, including
approximations by finite and countably categorical orders.
Closures are studied and ranks are described for families of order theories,
including the families of o-minimal and weakly o-minimal theories
of various signatures, as well as theories of pure linear orders with
various constraints on the discrete parts.
Keywords:
rank, approximation, family of theories, ordered theory.
