摘要：

It is shown that certain extremal correlators in four-dimensional N = 2 superconformal field theories (including N = 4 super-Yang-Mills as a special case) have a free-field functional form. It is further argued that the coupling constant dependence receives no correction beyond the lowest order. These results hold for any finite value of N-c. (C) 2000 Published by Elsevier Science B.V.
