چکیده
|
In this study, we derive the equation of motion in the framework of f(r) modified gravity with cosmological constant in an imperfect fluid . additionally, the extra force in the presence of cosmological constant for imperfect fluid is calculated. the field equations obtained from the variation of the action are utilized to achieve these results.
