| Abstract: | The derivation of string type equations from QCD is reexamined in the framework of renormalized perturbation theory. Renormalizing the equation for the second functional derivative of the Wilson functional at different points one observes a short distance problem which is studied by the help of OPE and RG. On this line the reduction of the equation to a linear one of string-type can be understood. |
