Errata to "Evaluation of zeta function of the simplest cubic field at negative odd integers"

Theorem 3.2 in the paper is incorrect since the left-hand side of equation (15) in [2] is multiplicative while the right-hand side is not. Therefore, Theorem 5.2 and Table 1, which use the result of Theorem 3.2, are wrong. However, the description of a Siegel lattice (Theorem 4.4) is correct. From the description of a Siegel lattice, using the methods in [1], we can compute the values of ζK(−1) for the first twentyfive simplest cubic fields, and the values of ζK(−3) and ζK(−5) for the first ten simplest cubic fields.
