SUMMARY
The discussion centers on the concept of adding a constant multiplied by the scalar field \(\phi\) to the D'Alembertian operator while maintaining relativistic invariance, as highlighted in Feynman's Lectures on Physics, Volume 2, Section 28-6. The key conclusion is that the sum of two invariant quantities remains invariant, and since the derivative of a constant with respect to any variable is zero, this addition does not disrupt the invariance. A mathematical proof is sought to further elucidate this concept.
