Abstract
In the sequelwe consider a contraction T on the real or complex Hilbert space \(\mathfrak{H}\), and its minimal unitary dilation U on the Hilbert space \(\mathfrak{K}\), real or complex, respectively \(\left( {\mathfrak{K}\supset\mathfrak{H}} \right)\). The linear manifolds
and their closures
play an important role in our investigations.
