Theorems corresponding to the concepts of stability discussed in works under reference should follow general pattern direct method Lyapunov. proved for such contain, as special cases results on - (i) origin, (ii) with respect some components, (iii) a set A, (iv) A (t), (v) conditional invariant B relative (vi) Stability asymptotic and (vii) A. It is shown that our properties can be extended cov...
