Algebraic Solution for the Källén-Pauli State Vectors in the Vθ Sector by a Congruence Transformation
C.A. Nelson · Journal of Mathematical Physics · 1972
From the representation of Bolsterli of the Vθ sector physical states in a basis having singular integral equations of the separable type, a congruence transformation carries the representation into the Källén-Pauli Heisenberg field components. This solves the Källén-Pauli singular integral equation algebraically. The resulting state vectors are proven explicitly to be both complete and orthonormal and furnish a new Möller wave matrix.
