140. Andreas Bernig:
Gromov-Hausdorff limits in definable families.

e-mail:

Submission: 2004, October 12.

Abstract:
The notion of piecewise definable metric space is introduced. It is shown that the set of all Gromov-Hausdorff limits of piecewise definable spaces belonging to a fixed bounded definable family is again a definable family. The Gromov-Haudorff limit is taken with respect to the geodesic metric and the word {\it definable} means {\it definable in some o-minimal structure over $\R$.
