Agarwal (Florida Institute of Technology), Grace (Cairo University) and O'Regan (University of Ireland) develop oscillation and non- oscillation theory for second order differential equations, with separate chapters addressing the solution of linear, half-linear, superlinear, and sublinear types of equations. Suitable for use as a graduate text, the book also discusses the oscillatory behavior of nonlinear two-dimensional differential systems and second order vector-matrix differential equations, and examines the behavioral properties of solutions of differential equations near infinity
