May 22, 2020 at 19:57 comment added Sandeep Silwal Amazing, I always learn something from fedja.
May 22, 2020 at 19:54 comment added Fedor Petrov @SandeepSilwal earlier it inspired fedja also to solve the coefficient problem for Fourier series (“The Bang solution of the coefficient problem”, St. Petersburg Math. J., 9:2 (1998), 407-419)
May 22, 2020 at 19:02 comment added Sandeep Silwal Thanks @FedorPetrov. It seems that this argument has inspired other results around here as well, like this one by fedja: mathoverflow.net/questions/352720/…
