On block completion problems for \(j_{qq}-J_ q\)-inner functions. I: The case of a given block column
This paper studies various block completion problems for \(j_{qq}\)-\(J_ q\)-inner functions where a \(2q\times q\) block column is given. Necessary and sufficient conditions for the solvability of the problems are given. If solutions exist, then a complete description of the set of all solutions is stated.
