Feynman graphs and related Hopf algebras
<|reference_start|>Feynman graphs and related Hopf algebras: In a recent series of communications we have shown that the reordering problem of bosons leads to certain combinatorial structures. These structures may be associated with a certain graphical description. In this paper, we show that there is a Hopf Algebra structure associated with this problem which is, in a certain sense, unique.<|reference_end|>
