On some completion problems for various subclasses of \({\mathcal J}_{pq}\)- inner functions
Summary: Several completion problems of the following type will be studied: Given meromorphic matrix-valued functions \(f\) and \(h\), the question is to describe the set of all \(j_{pq}\)-inner functions \(W\) which have the block structure \(W={*\;f\choose *\;h}\).
