Oscillation Theorems for Nonlinear Ordinary Differential Equations of Even Order
Consider the differential equation 1 where n is even and f(t, y) is subject to the following conditions: (a) f(t, y) is continuous on [0, ∞)× R ; (2) (b) f(t, y) is nondecreasing in y for each fixed t∈[0,∞) ; (c) yf(t, y ) > 0 for y ≠ …
