含αR^2+γR_(μν)R^(μν)项的宇宙暴涨

Inflation Cosmology with αR^2+γR_(μv)R_(μv)

我们利用含αR^2+γR_(μv)R^(μv)项的宇宙理论同带有一个标量场φ的Einstein理论之间的等价性,讨论了该宇宙的暴涨行为.结果表明,在D维空时(D>2)中,存在指数型的暴涨解.

Using the equivalence between the theory with Ricci tensor and corvature squared term and the Einstein theory with a scalar field, we discuss inflationary behavior of the universe. It is shown that when D > 2, there exists exponential-type inflation.
