Abstract

We try to bound the denominators of standard L-functions attached to Siegel modular forms when we twist them by Dirichlet characters. Main tools are our modification of the doubling method (Böcherer et al., Ann. Inst. Fourier 50:1375–1443, 2000) together with its application to congruences by the method of Katsurada (Math. Z. 259:97–111, 2008) and integrality properties of Bernoulli numbers with characters.
