On a Class of Variational Principles for Solving the Lippmann‐Schwinger Equation
Jiřı́ Horáček · AIP conference proceedings · 2008
It is shown that the method of continued fractions proposed by Horáček and Sasakawa generates a sequence of Schwinger‐like variational principles for the scattering T‐matrix. Together with the variational principles, restrictions on the trial function may also be defined. Preliminary calculations show fast convergence of the method.
