%0 Journal Article %A Escribano Martínez, Jesús %T Approximation theorems in o-minimal structures %D 2002 %@ 0019-2082 %U https://hdl.handle.net/20.500.14352/58904 %X We prove that, in any o-minimal structure, definable C-r mappings can always be approximated by definable Cr+1 mappings. As an application we obtain definable triviality for pairs of definable proper submersions. %~
