摘要：
A proof for a non-perturbative C-theorem in four dimensions, capturing the irreversibility of the renormalization group flow in the space of unitary quantum field theories, has not been accomplished, yet. We test the conjectured C-theorems using the exact results recently obtained in N = 1 supersymmetric gauge theories. We find that the flow towards the infrared region is consistent with the main proposals for a C-theorem.
