Abstract
In connection with renormalization problems in quantum field theory, Pfaffians and Hafnians are considered. A noteworthy expansion of determinants and permanents is given, in terms of Pfaffian-like and Hafnian-like objects, that immediately leads to the known reduction of a determinant to a single Pfaffian. Finally, some auxiliary results are presented.File in questo prodotto:
