From the reviews: "The monograph under review is a very successful attempt to collect and systematically present numerous oscillation or nonoscillation criteria for various classes of linear and nonlinear differential equations and related results on asymptotic behavior of solutions ... . The book is nicely written and the selection of the material is very interesting ... . The book is a welcome addition to the existing literature on oscillation and shall be useful for researchers and graduate students in differential equations ... ." (Yuri V. Rogovchenko, Zentralblatt MATH, Vol. 1073 (24), 2005)
