Abstract
Bounded composition operators with matrix symbols on L 2 ( μ ) , where μ is a positive Borel measure with a Laplace type density function on the d-dimensional Euclidean space, are studied. Hyponormality and subnormality of adjoints of such operators are characterized explicitly in terms of their symbols.
