. Nonlocal constants are functions that are constant along motion but whose value depends on the past history of the motion itself. They are a powerful tool to provide ﬁrst integrals in classical mechanics and, in this respect, a new approach to get nonlocal constants within the framework of lagrangian scalar ﬁeld theory is introduced. We derive locally-conserved currents from them, and we prove the consistency of our results by recovering some standard Noetherian results. Applications include…

The work shows that the cosmological constant can be considered as a second order correction to the Newtonian gravity and shows the emergence of a theory-derived quantum CPTD that allows to have a stable quantum vacuum without postulating a non-zero classical CC.
