摘要
The paper is devoted to an oscillation theorem for the second-order forced linear differential equation of the form (p(t)x')' + q(t)x = g(t) . The sign of the coefficient q is not definite, and the function g is not necessarily the second derivative of an oscillatory function. The question raised by J. Wong in Second order nonlinear forced oscillations (SIAM J. Math. Anal. 19 (1988), 667-675) is answered. A region of oscillation of Mathieu's equation is specified.
