Non-static Einstein–Rosen universe with scalar field is examined via two different selection of f(R,T) models. Firstly, we analyzed Einstein–Rosen universe with scalar field in f(R,T)=R+2f(T) model. Then, we constructed field equations for f(R,T)=f1(R)+f2(R)f3(T) model, as well. For both models, exact solutions of field equations have been attained without considering any approximation or restriction. Whether scalar field corresponds to phantom and/or quintessence scalar field are investigated for each models.

具有标量场的爱因斯坦-罗森宇宙 F[RŤ 理论

通过两种不同的选择来检验具有标量场的非静态爱因斯坦-罗森宇宙 F[RŤ楷模。首先,我们用标量场分析了爱因斯坦-罗森宇宙F[RŤ=[R+2FŤ模型。然后,我们构造了用于F[RŤ=F1个[R+F2[RF3Ť模型。对于这两种模型,都无需考虑任何近似或约束即可获得场方程的精确解。对于每个模型,研究标量场是否对应于幻像和/或典型标量场。
