Unitarized perturbation theory in quasipotential approach
Description
The iterational procedure, which allows to construct the complete sets of functions satisfying the quasipotential equation within a required accuracy, is suggested. The method is employed for construction of the function which satisfies the Lippmann-Shwinger type equation up to the second order terms in the quasipotential and, besides, the unitarity and completeness conditions. The analytic properties of this function are studied
