Abstract
We present an o-minimal version of Michael’s selection theorem. One variant of this theorem is known for definable multivalued mappings with closed $M$-Lipschitz cell values. We extend these results to include maps with values being standard definable cells. Furthermore, the Lipschitz condition is weakened to equicontinuity (in a sense given in the paper).
