Algebro-geometric Feynman rules
Paolo Aluffi, Matilde Marcolli
We give a general procedure to construct algebro-geometric Feynman rules, that is, characters of the Connes-Kreimer Hopf algebra of Feynman graphs that factor through a Grothendiec…

Chern classes of blow-ups
Paolo Aluffi
We extend the classical formula of Porteous for blowing-up Chern classes to the case of blow-ups of possibly singular varieties along regularly embedded centers. The proof of this…

Feynman motives of banana graphs
Paolo Aluffi, Matilde Marcolli
We consider the infinite family of Feynman graphs known as the "banana graphs" and compute explicitly the classes of the corresponding graph hypersurfaces in the Grothendieck ring…
