摘要

In this paper, we will describe a recursive formula of multiple Eulerian polynomials and then we prove that all roots of these polynomials are negative real numbers. On the other hand, extending Euler’s techniques to calculate the zeta values at negative indices, we also give a new way to regularize the polyzetas at nonpositive integer multi-indices.
