[en] For k ≤ n, let E(2n,k) be the sum of all multiple zeta values with even arguments whose weight is 2n and whose depth is k. Of course E(2n,1) is the value ζ(2n) of the Riemann zeta function at 2n, and it is well known that E(2n,2)=(3)/(4)ζ(2n). Recently Z. Shen and T. Cai gave formulas for E(2n,3) and E(2n,4) in terms ζ(2n) and ζ(2)ζ(2n-2). We give two formulas form E(2n,k), both valid for arbitrary k≤n, one of which generalizes the Shen-Cai results; by comparing the two we obtain a Bernoulli-number identity. We also give an explicit generating function for the numbers E(2n,k).
