Abstract: | ||||||||||||||||
Strong cell decomposition property has been proved in non-valuational weakly ominimal
expansions of ordered groups. In this note, we show that all o-minimal traces
have strong cell decomposition property. Also after introducing the notion of irrational
nonvaluational cut in arbitrary o-minimal structures, we show that every expansion of
o-minimal structures by irrational nonvaluational cuts is an o-minimal trace.
