论文摘要
我们表明，Fré，Sagnotti和Sorin（核物理学\ textbf {b 877}（3）（2013），1028--1106）考虑的几个可集成（即，可以解决的）标量宇宙学可以推广，可以将空间弯曲不为s scaliation n scaliation或per pr^scaliation cliatiation（2013）（2013），1028--1106）。 = w \，ρ^{（m）} $;根据该领域的自我交互潜力的特定形式，常数$ w $可以是任意的，也可以适当地固定。
We show that several integrable (i.e., exactly solvable) scalar cosmologies considered by Fré, Sagnotti and Sorin (Nuclear Physics \textbf{B 877}(3) (2013), 1028--1106) can be generalized to include cases where the spatial curvature is not zero and, besides a scalar field, matter or radiation are present with an equation of state $p^{(m)} = w\, ρ^{(m)}$; depending on the specific form of the self-interaction potential for the field, the constant $w$ can be arbitrary or must be fixed suitably.
