Joint online scientific meeting with the American University of Beirut, Lebanese University in Fanar, and the University of Potsdam in the framework of the cooperation:
AT THE CONFLUENCE OF GEOMETRY, ANALYSIS AND MATHEMATICAL PHYSICS
Abstract: In joint work with Bin Zhang, we renormalize divergent Feynman amplitudes appearing in Quantum Field Theory by spectral zeta regularization involving many complex parameters. I will explain our results in some pedagogical way and using some examples to illustrate the difficulties.
