Multiple zeta values at non-positive integers Shigeki Akiyama and Yoshio Tanigawa
 

Summary: Multiple zeta values at non-positive integers
Shigeki Akiyama and Yoshio Tanigawa 
Abstract. Values of Euler-Zagier's multiple zeta function at non-positive integers
are studied, especially at (0; 0; : : : ; n) and ( n; 0; : : : ; 0). Further we prove a
symmetric formula among values at non-positive integers.
Key words: Multiple zeta function, Bernoulli numbers, Stirling numbers

One of remarkable properties of the Riemann zeta-function (s) is that
