What are the key features of the breitenlohner-freedman stability bound in quantum field theory?
The key features of the Breitenlohner-Freedman stability bound in quantum field theory are the constraints it places on the masses and couplings of fields in a theory to ensure the theory is stable and does not exhibit tachyonic instabilities. This bound helps to prevent the theory from becoming physically inconsistent and ensures its mathematical and physical consistency.

What are the key features of non-perturbative methods in quantum field theory?
Non-perturbative methods in quantum field theory are used to study systems where traditional perturbation theory does not work. Key features include the ability to analyze strong interactions, study non-linear effects, and explore phenomena such as confinement and spontaneous symmetry breaking. These methods provide a more comprehensive understanding of quantum field theory beyond simple perturbative calculations.
