Rui Dong, Masoud Khalkhali, Walter D. van Suijlekom
We consider both the bosonic and fermionic second quantization of spectral triples in the presence of a chemical potential. We show that the von Neumann entropy and the average ene…

Renormalization Hopf algebras for gauge theories and BRST-symmetries
Walter D. van Suijlekom
The structure of the Connes-Kreimer renormalization Hopf algebra is studied for gauge theories, with particular emphasis on the BRST-formalism. We work in the explicit example of q…
