Renormalization of multiple zeta values

  title={Renormalization of multiple zeta values},
  author={Li Guo and Bin Zhang},
Multiple zeta values (MZVs) in the usual sense are the special values of multiple variable zeta functions at positive integers. Their extensive studies are important in both mathematics and physics with broad connections and applications. In contrast, very little is known about the special values of multiple zeta functions at non-positive integers since the values are usually singular. We define and study multiple zeta functions at integer values by adapting methods of renormalization from… CONTINUE READING
