Oscillation criteria for matrix differential equations with oscillatory coefficients

  • H. C. Howard


This paper considers the matrix differential equation Y″(x)+P(x)Y(x)=0 (and several generalizations) and establishes sufficient conditions for the existence of zeros of some of its solutions (in the sense that determinant Y(x)=0) when the coefficient P is « oscillatory ».
