Integrate by parts the d'alembertian of a 4-variable function

  1. Aug 12, 2011 #1
    Can you please tell me how to integrate by parts the d'alembertian of a 4-variable function over a volume dx * dy * dz * dt. I have stumbled upon this seemnigly simple exercise on my way to understanding QFT of scalar fields.
