[[Alexander Zamolodchikov]] proved in 1986 that two-dimensional quantum field theory always has such a ''C''-function. Moreover, at fixed points of the RG flow, which correspond to [[conformal field theory|conformal field theories]], Zamolodchikov's ''C''-function is equal to the [[central charge]] of the corresponding conformal field theory,<ref>[[Alexander Zamolodchikov|Zamolodchikov, A. B.]] (1986). [http://www.jetpletters.ac.ru/ps/1413/article_21504.pdf "Irreversibility" of the Flux of the Renormalization Group in a 2-D Field Theory], ''JETP Lett'' '''43''', pp 730–732.</ref> and roughly counts the degrees of freedom of the system.
Until recently, it had not been possible to prove an analog ''C''-theorem in higher-dimensional quantum field theory. However, in 2011, Zohar Komargodski and Adam Schwimmer of the [[Weizmann Institute of Science]]
