   <abstract xml:lang="ru">
    <p>Рассмотрена задача о периодических по времени решениях волнового уравнения с переменными коэффициентами общего вида и заданной периодической вынуждающей силой. В случае однородных граничных условий 3-го рода и Дирихле доказано существование  счетного числа периодических  решений при условии, что нелинейное слагаемое имеет степенной рост без предположения монотонности.</p>

    <p>The problem of time periodic solutions of a wave equation with floating factors of a general type and a specified periodic driving force is considered. In case of homogeneous boundary conditions of the third type and Dirichlet the existence of a denumerable number of periodic solutions at the condition that a nonlinear item has a power growth without the assumption of monotony is proved.  </p>
