摘要

我们在[公式:见文]中给出了具有倾斜同余和创造场的重力的大撕裂奇点。我们通过考虑共形平坦宇宙和条件(公式:见文)来求解场方程，其中[公式:见文]是一个常数。用[J]的方法研究了场方程的解。V. Narlikar和T. Padmanabhan，物理学家Rev. D 32, 1928(1985)]，其中创造场[公式:见文]是时间的函数[公式:见文]。利用MATLAB对该模型的一些几何方面进行了讨论。

Big Rip singularity in f(R,T) gravity with tilted observers

We have presented the Big Rip singularity in [Formula: see text] gravity with tilt congruences and creation field. We have solved the field equations by considering a conformally flat universe and the condition [Formula: see text], where [Formula: see text] is a constant. The solutions of the field equations have also been investigated by using the method of [J. V. Narlikar and T. Padmanabhan, Phys. Rev. D 32, 1928 (1985)] in which the creation field [Formula: see text] is a function of time [Formula: see text]. Some geometric aspects of the model are also discussed by using MATLAB.
