| Abstract: | Mixed-type differential inequalitiesand mixed-type differential equationare studied. A sufficient condition has been obtained for (A),(B) and (C)respectively, i.e. (A) has no eventually positive solution, (B)has no eventually negative solution and(C) has only oscillatory solutions. Necessary and sufficient coditions of the relevtnt problems have been gotten for (A) ,(B) and (C) with constant coefficients. |
