On a property of the stable or conditionally stable solutions of systems of non-linear differential equations

Summary Qualitatively expressed me assert the following. If the equation (1.1)·(1.2) fulfills the restriction(1.6)·(1.7)·(1.8) whic are less restrictive than usual, then all solutions with norms tending to O with1/t cannot be ?to small? in an arbitrary interval in t ≧ 0 with fixed length.
