Summary
Analyticity properties of Green’s functions are studied with respect to a parameter ε that measures a symmetry breaking in the Hamiltonian.
Riassunto
Si studiano le proprietà di analiticità di funzioni di Green rispetto a un parametro ε che misura una rottura di simmetria nell’hamiltoniana.
Реэюме

IfA is a scattering amplitude, thenB(0 ...) ∼μ p due to the Adler consistency condition (3); soA(0, ...) ∼μ p lnμ.
