Abstract
The simplest way to introduce a function \(f_{{V_0}}^V(r,r')\) which is a solution of (XI.3.1) and which depends on a sequence of parameters {cμ} is to construct a linear combination of products \(\varphi _\mu ^{{V_0}}(r)\varphi _\mu ^{{V_0}}(r')\) with coefficients cμ. An alternative method might introduce products with strong consistency conditions. In all cases, a relation between {cμ} and {δl} must be found by investigating the asymptotic behavior of \(\varphi _l^V(r)\). This aim is achieved in the matrix methods we present in this chapter. They yield potentials in special classes that are defined by the nature of {μ}. We strictly limit our study to real potentials.
