*Abstract:
We work over an o-minimal expansion of a real closed field R. Given a
closed simplicial complex K and a finite number of definable subsets of its
realization |K| in R we prove that there exists a triangulation (K',f) of |K|
compatible with the definable subsets such that K' is a subdivision of K and f
is definably homotopic to the identity on |K|.*
