Abstract

We obtained sufficient conditions for <TEX>$\phi$</TEX>(t)-stability and uniform <TEX>$\phi$</TEX>(t)-stability of the trivial solution of comparison differential system. we also investigated the corresponding stability concepts of the trivial solution of the differential system using the thoery of differential inequlities through cones and the method of conevalued Lyapunov functions.
