Matrix perturbation theory G. W. Stewart, Ji-guang Sun
Publisher: Academic Press

This chapter lays down the ideas of path-integrals ready for QFT. Publisher: JAI Press Page Count: 443. And the perturbation lambda appears as a square. The matrix element appearing in the numerator is squared. Imagine that the nodes of the graph were golf balls tied together by strings (which stand for edges). Language: English Released: 2003. Topics which are covered include: matrix perturbation theory; systems of ordinary differential equations with small parameter; reconstruction and equations in partial derivatives. Topics covered here include perturbation theory & S-matrices and Coulomb scattering. Another interesting explanation is the one offered by matrix perturbation theory.
