论文摘要
对于具有标量场的二次重力理论，在Shapovalov〜I〜型型空间中发现了重力波模型的精确解，这在相对论的一般相对论的模型中并未产生。所考虑的重力理论可以有效地描述宇宙动力学的早期阶段。 I型Shapovalov空间是重力波shapovalov的最通用形式，其特权坐标系统中的度量取决于三个变量，包括波变量。对于爱因斯坦真空的空位，这些波模型退化为更简单的类型。重力理论中获得的重力波的精确模型可用于检验这种重力理论的现实主义。
For the quadratic theory of gravity with a scalar field, exact solutions are found for gravitational-wave models in Shapovalov~I~type spacetimes, which do not arise in models of the general theory of relativity. The theory of gravity under consideration can effectively describe the early stages of the dynamics of the universe. Type I Shapovalov spaces are the most general form of gravitational-wave Shapovalov spacetimes, whose metric in privileged coordinate systems depends on three variables, including the wave variable. For Einstein vacuum spacetimes, these wave models degenerate into simpler types. The obtained exact models of gravitational waves in the quadratic theory of gravity can be used to test the realism of such theories of gravity.
