Abstract
It is shown that certain extremal correlators in four-dimensional N = 2 sup
erconformal field theories (including N = 4 super-Yang-Mills as a special c
ase) have a free-field functional form. It is further argued that the coupl
ing constant dependence receives no correction beyond the lowest order. The
se results hold for any finite value of N-c. (C) 2000 Published by Elsevier
