Oscillations of second-order sub-linear delay differential equations with impulses

, 2016
By employing classical integral inequalities, the sufficient and necessary conditions for a second-order sub-linear delay differential equation with impulses to be oscillatory are established.

SUBHARMONIC SOLUTIONS NEAR AN EQUILIBRIUM POINT FOR n HAMILTONIAN SYSTEMS

-In-thiswork we study-subharmonic solutions near an equilibrium point for %he Hamiltonian system z JA(t)z + JHt..(z, t) where A(t) is a matrix, fl,(z,t) = o(I z 1) and both A and H are periodic in t. On the linear part of the system we impose a condition
