Abstract: | New oscillation criteria are given for the second order sublinear differential equation where a C1 ([t0, )) is a nonnegative function, , f C() with (x) 0, xf(x) / (x) > 0 for x 0, , f have continuous derivative on {0} with [f(x) / #x03C8;(x)] 0 for x 0 and q C([t0, )) has no restriction on its sign. This oscillation criteria involve integral averages of the coefficients q and a and extend known oscillation criteria for the equation x (t) + q(t)x(t) = 0. |
