رفتار مجانبي متفاوت فضا زمان در گرانش F(R)

Various Asymptotic behavior of spacetime in F(R) Gravity

در این مقاله با در نظر گرفتن یك كلاس خاص از گرانش F R ، جواب های متقارن كروی را برای متریكی با رفتار مجانبی متفاوت بدست می آوریم. ... In this paper, we obtain spherically symmetric solutions of a metric with various asymptotic behavior by considering a special class of F(R) gravity. We find that the asymptotic behavior of the mentioned spacetime is neither flat nor (anti) deSitter, but we may achieve these behaviors by adjusting some free parameters. Then, we investigate the solution properties for various cases and analyze essential singularities, temperature and stability of the mentioned gravity
