Mar 23, 2021 at 20:20 comment added Dima Pasechnik Fichtenholz introduces $J_v$ only for integer $v$, so that's why he remarks that the meaning of $J_{n/2}$ for $n$ odd needs extra work, not done in the book.
Mar 23, 2021 at 20:06 comment added Dima Pasechnik [395,14)] is a local reference, to vol II, where $J_v$ (Bessel function/бесселева функция) is defined.
Mar 23, 2021 at 19:55 comment added Francois Ziegler Thanks! This is not quite (1) but indeed, strongly suggests that Sonine may have had (1) in whatever source Fichtenholz is drawing from. Too bad he doesn’t seem to say! (What’s “[395, 14)]”?)
Mar 23, 2021 at 16:55 comment added Dima Pasechnik Sonin's last listed publication appeared in 1903, so probably even earlier: zbmath.org/?q=au%3A+sonine
