Abstract : A convenient expression for the normalization of the T-matrix pole term is given. The method of polology is applied to various processes. The coupling constant of the N lambda K interaction is determined from the antiproton + p lambda + anti lambda angular distribution. Further application of the method to sigma(0)-K(0) production from pion-proton interactions and sigma hyperon-pion production from K(-)+p interactions indicate that the sigma-lambda relative parity is even, although this conclusion cannot be considered firm. This constitutes support for the hypothesis of global symmetry. Some additional applications of polology are suggested and discussed. (Author)
