标题： Open Universe Model: Description by Mathieu Functions

摘要： 考虑了由共形平坦的四维度规描述的开宇宙的一个模型。 引力方程以完善的帕斯卡流体为源，被简化为非线性振动方程。 提出将此方程视为包含某些宇宙学模型的马蒂厄方程。 表明宇宙状态函数的行为在定性上与大爆炸情景一致。 显示英文摘要

摘要： A model of the open Universe described by a conformally flat 4-metric is considered. The gravitational equations with a perfect Pascal fluid as a source are reduced to the nonlinear equation of oscillations. It is proposed to consider this equation as the Mathieu equation encompassing some cosmological models. It is shown that the behaviour of the Universe state function is in qualitative accordance with the Big Bang scenario.
