Oscillation Results for Second Order Matrix Differential Equations with Damping

Yasemin Bascı, Aydın Tiryaki

By using the positive linear functional, including the general means and Riccati technique, some new oscillation criteria are established for the second order matrix differential equations (r(t)P(t)ψ(X(t))K(X (t))) + p(t)R(t)ψ(X(t))K(X (t)) + Q(t)F(X (t))G(X(t)) = 0, t ≥ t 0 > 0. The results improve and generalize those given in some previous papers.
