## Boundedness criteria and norm of some multilinear Hilbert-type operators.(English)Zbl 1470.44003

Summary: We consider two families of multilinear Hilbert-type operators for which we give exact relations between the parameters so that they are bounded. We also find the exact norm of these operators.
