Weakly o-minimal structure

From Wikipedia, the free encyclopedia

[edit] Weakly O-Minimal Definition

A linearly ordered structure, m, with language L including an ordering relation < , is called weakly o-minimal (w.o.-minimal) iff every parametrically definable subset of m is a finite union of convex(definable) subsets. A theory is w.o.-minimal iff all its models are w.o.-minimal.[1]
