Homework Help: Please Help me with d'alembertian

  1. Nov 30, 2008 #1
    Hi. I am new in here. So i am not fully sure whether i should post it here. But please help me if u can.
    Let V be the potential of gravitational field and i will write d'alembertian as D the equation is:
    V DV = 4 pi T
    here T is the trace of the stress energy tensor. Now how can i find the equation of motion in these field. I have used the lagrangian equation but to no avail. And i should also mention to u that i am not even a university student. I am a college student. So please try to elaborate it if u can. And please also give a detail about the term u may use. Because i may not know them.
