Query: Uniform boundedness of derivatives of meromorphic inner functions on the
  real line   Inner functions are an important and popular object of study in the field of
complex function theory. We look at meromorphic inner functions with a given
spectrum and provide sufficient conditions for them to have uniformly bounded
derivatives on the real line. This question was first studied by Louis de
Brange in 1968 and was later revived by Anton Baranov in 2011.
