Correction to: Math. Ann. 289:589–612 (1991) https://doi.org/10.1007/BF01446591 Abstract Correction to my paper on the poles of standard L-functions attached to Siegel modular forms. Mathematics Subject Classification 11F46 · 11F66 In the second corollary of Theorem 3 of the original paper [5, p. 601], I made a statement (without proof) on the orders of possible poles of the completed standard L-function (s, f , St) attached to a Siegel modular form f of weight k and degree n in case k < n. It asserts in particular that the orders of poles are at most two, but this is not the case. This error was pointed out by a mail from Professor Chenevier on October 27, 2018 (for details, see the remark below). After that I checked the paper again and noticed that I had made some mistakes in deducing the claim. To state the corrected version the following notation will be used. For n, k ∈ Z>0 let Skn be the space of holomorphic cusp forms of weight k for  (n) := Sp(n, Z) = Sp 2n (Z) . Let f ∈ Skn be a Hecke eigenform and L(s, f , St) be the standard L-function attached to f . Take ε, ν ∈ {0, 1} such that n ≡ ε (mod 2) and k ≡ ν (mod 2). Let s  s , C (s) := 2(2π )−s (s) R (s) := π − 2  2

By Böcherer [1], (s, f , St) has a meromorphic continuation to the whole s-plane and is invariant under the substitution s → 1 − s. The symbol ords=c stands for the order of zero of a meromorphic function at s = c. The largest integer ≤ x is denoted by [x]. Now we state the correction. The second corollary of Theorem 3 in [5] should be replaced by the following Proposition 1 Suppose k < n. Then the possible poles of (s, f , St) are contained in [−n + k − ν, n − k + ν + 1] ∩ Z and for every m ∈ [1, n − k + ν + 1] ∩ Z we have  ords=m (s, f , St) ≥
