![عکس صفحه اول مقاله: On the rapid decay of cuspidal automorphic forms On the rapid decay of cuspidal automorphic forms](/preview/png/6425928.png)
Many important analytic statements about automorphic forms, such as the analytic continuation of certain L-functions, rely on the well-known rapid decay of K-finite cusp forms on Siegel sets. We extend this here to prove a more general decay statement along sets much larger than Siegel sets, and furthermore state and prove the decay for smooth but not necessarily K-finite cusp forms. We also state a general theorem about the convergence of Rankin-Selberg integrals involving unipotent periods, closing a gap in the literature on L-functions. These properties serve as the analytic basis (Miller and Schmid, 2009Â [15]) of a new method to establish holomorphic continuations of Langlands L-functions, in particular the exterior square L-functions (Miller and Schmid, 2009Â [16]) on GL(n).
