Abstract
Iterative techniques of the solution of the decoupling equation are us ed to construct various types of effective Hamiltonians in the framewo rk of nonorthogonal transformations. A general and numerically conveni ent Hermitization procedure of the non-Hermitian Hamiltonians obtained by such techniques is proposed and the definition of effective operat ors with the related normalization problems is reviewed.
