Covariant classical field theory

Covariant classical field theory is a framework in theoretical physics that describes the dynamics of fields in a way that is consistent with the principles of relativity. It emphasizes the importance of covariance—specifically, Lorentz covariance—meaning that the laws of physics take the same form in all inertial reference frames. ### Key Concepts: 1. **Fields**: In classical field theory, fields are physical quantities defined at every point in space and time. Common examples include electromagnetic fields and gravitational fields.
