Michael's Theorem for a Mapping Definable in an O-Minimal Structure on a Set of Dimension 1.

e-mail: ,

Submission: 2016, April 14.

Let R be a real closed field and let some o-minimal structure extending R be given. Let F : A -> R^m be a definable multivalued lower semicontinuous mapping with nonempty definably connected values defined on a definable subset A of R^n of dimension 1 (A can be identified with a finite graph immersed in R^n ). Then F admits a definable continuous selection.

Keywords and Phrases: Michael's selection theorem, o-minimal structure, finite graph.
