Tolman-Oppenheimer-Volkoff equations in non-local $f(R)$ gravity

Understand

Non-local $f(R)$ gravity was proposed as a powerfull alternative to general relativity (GR) .

• This theory has potentially adverse implications for infrared (IR) regime as well as ultraviolent(UV) early epochs.
• However, there are a lot of powerful features, making it really user-friendly.
• A scalar-tensor frame comprising two auxiliary scalar fields, used to reduce complex action.
