Abstract
Some objections concerning the validity of a new nonperturbative treatment of multiphoton processes ("momentum-translation approximation") are presented and discussed. In the present state of the question, it seems that the multiphoton amplitudes given by this theory cannot be considered as reliable.Keywords
