Abstract
We show that some calculations of pion emission based on current algebra need model-dependent corrections even in the limit of zero four-momenta. The corrections are ambiguous and depend on the way in which the limit is reached. We obtain by means of Fubini's method general rules to know when to expect the corrections.Keywords
