| Abstract: | Vectorial Hankel operators are studied, in particular the ranges of Hankel operators induced by sums and products of matrix functions defined on the unit circle are determined. The analytical tools involve factorization theorems for operator valued analytic functions and the spectral analysis of operators that intertwine restricted shifts. |
