Oscillation and nonoscillation properties for second order nonlinear differential equations,We survey oscillation and nonoscillation criteria for the generalized Emden-Fowler differential equation y″+q(x)y.=0, q>0, γ>0 with particular emphasis on the duality between the sublinear and superlinear cases.

In particular we consider a generalized Burgers‘ equation and we sketch a method for solution in series by using the theory of Sobolevskij and Tanabe. Then we study the KdV equation with nonuniformity terms and we describ
