标题： Gravitational Field of the Early Universe: I.Non-linear Scalar Field as the Source

摘要： 在本文综述文章中，我们考虑了早期宇宙引力场的三个最重要的来源：自相互作用标量场、手征场和规范场。指出了它们之间的对应关系。更加关注非线性标量场作为引力的来源。回顾了在暴胀宇宙中寻找精确解的进展。讨论了“势的精细调节”方法的基本思想，并详细介绍了计算背景。获得了一组标准暴胀模型和共形平坦时空的新的精确解。特别关注“势的精细调节”与巴罗方法之间的关系。作为两种方法综合的例子，获得了新的精确解。 显示英文摘要

摘要： In this review article we consider three most important sources of the gravitational field of the Early Universe: self-interacting scalar field, chiral field and gauge field. The correspondence between all of them are pointed out. More attention is payed to nonlinear scalar field source of gravity. The progress in finding the exact solutions in inflationary universe is reviewed. The basic idea of `fine turning of the potential' method is discussed and computational background is presented in details. A set of new exact solutions for standard inflationary model and conformally-flat space-times are obtained. Special attention payed to relations between `fine turning of the potential' and Barrow's approaches. As the example of a synthesis of both methods new exact solution is obtained.
