{wiki=Lagrangian_(field_theory)}
In the context of field theory and theoretical physics, the Lagrangian is a mathematical function that encapsulates the dynamics of a system. It is a central concept in the Lagrangian formulation of mechanics, which has been extended to fields in the context of quantum field theory and classical field theory.
