Summary:
- Quantum Field Theory (QFT) is a fundamental theory in physics that describes the behavior of subatomic particles and their interactions.
- Lorentz covariance is a key principle in QFT, which states that the laws of physics must be the same for all observers moving at constant velocities relative to each other.
- This article discusses how Lorentz covariance is essential for the consistency and mathematical structure of QFT, ensuring that the theory is compatible with the principles of special relativity.
