We study asymptotic behavior of eventually positive increasing solutions to the half-linear equation $(r(t)|y'|^{alpha-1}sgn y')'=p(t)|y|^{alpha-1}sgn y$, where $r,p$ are positive continuous functions and $alphain(1,infty)$. We give conditions which guarantee that any such a solution is in the class $Gamma$ (in the de Haan sense). We also discuss regularly varying solutions and connections with a generalized regular variation and other related concepts. The results can be viewed as a half-linear extension of existing statements for linear equations, but in some aspects they are new also in the linear case.
