Abstract
We discuss the threshold tree amplitudes in different nonintegrable qu antum field theories in the framework of integrability. The amplitudes are related to some Baker functions defined on the auxiliary spectral curves and the nullification phenomena are shown to allow a topologic al interpretation.
