Abstract:We investigate the asymptotic behavior at $+infty$ of non-oscillatory solutions to differential equations $y'=G(t,y), t>a$, where $Gcolonmathbb{R} ^{1+l}tomathbb{R} ^l$ is definable in a polynomially bounded o-minimal structure. In particular, we show that the Pfaffian closure of a polynomially bounded o-minimal structure on the real field is levelled.
