The main tool used is a generalized Riccati transformation and the standard integral averaging technique.&lt;/p&gt;

These results improve and generalize some known oscillation criteria due to G. J. Butler, L. H. Erbe and A. B. Mingarelli [1], N. Parhi and P. Praharaj [2] for self-adjoint second order matrix differential systems, and Yang et. al. [4] for linear matrix Hamiltonian systems.&lt;/p&gt;
