For … WebJul 15, 2024 · The closure statement of Bessel functions is a well known result and is often used initial value problems. So there is no doubt that it is true (See for example p. 696 in Arfken, Weber or Morse and Feshbach, Section 6.3). I also found an answer on here, where the closure relation was used to determine initial conditions. o2 wolfenbüttel forum
