Cy. Zhang, PSEUDO ALMOST-PERIODIC SOLUTIONS OF SOME DIFFERENTIAL-EQUATIONS .2., Journal of mathematical analysis and applications, 192(2), 1995, pp. 543-561
We first present some results about pseudo almost periodic functions.
Then we use these results to show some theorems about existence and un
iqueness of the pseudo almost periodic solutions of the linear and the
quasi-linear nonautonomous equations. Finally we set up some theorems
of the existence of pseudo almost periodic solutions implying the exi
stence of almost periodic solutions of general ordinary differential e
quation systems. (C) 1995 Academic Press, Inc.
