Oscillation Criteria for Matrix Differential Equations
Oscillation Criteria for Matrix Differential Equations
We shall be concerned at first with some properties of the solutions of the matrix differential equation 1.1 where is an n × n symmetric matrix whose elements are continuous real-valued functions for 0 < x < ∞, and Y(x) = (y ij (x)), Y″(x) = (y″ ij (x)) are …
