Sufficient conditions for the oscillation of solutions to the differential system X ( t ) + A ( t ) X ( t ) = 0 X(t) + A(t)X(t) = 0 are established which are valid when the matrix A is not symmetric. An example is given to demonstrate that a condition known to be sufficient for the oscillation of solutions when A is symmetric is not valid in the nonsymmetric case.
