The analyticity and unitarity hypotheses for a general transition amplitude are formulated carefully for a world containing only one type of particle. From these hypotheses follows the conclusion that the general transition amplitude has no singularities on the positive real energy axis other than isolated singularities at physical thresholds. The analyti c behavior near each such singularity is exhibited. At thresholds for processes involving an odd number of particles, the behavior is logarithmic. (auth)
