SUMMARY

Zeta regularization is a method utilized to handle ultraviolet (UV) divergences in quantum field theory. The discussion references a specific paper, arXiv:0906.2418, which presents a treatment of divergent integrals using zeta regularization, particularly in Section 2. The approach involves manipulating divergent series to yield finite results, a technique that is widely accepted in theoretical physics. The validity of this method is supported by similar findings in another document linked in the discussion.

PREREQUISITES
  • Understanding of quantum field theory principles
  • Familiarity with zeta regularization techniques
  • Knowledge of divergent series and their manipulation

Zeta regularization for UV divergences ??

I know that zeta regularization makes sense but is this paper correct ?

http://arxiv.org/ftp/arxiv/papers/0906/0906.2418.pdf

watched on arxiv by a chance, there are 2 sections the 'divergent integral' treatment by using zeta regularization is on section 2

http://www.scribd.com/doc/9650858 provided the same results.

i am not an expert but i think he is taking divergent series in order to obtain finite results is this acceptable ??
