On Some Classes of Extensions of Sectorial Operators and Dual Pairs of Contractions,Some classes of contractive and noncontractive extensions of a dual pair of contractions are investigated. A problem of a description of the set of all .-sectorial extensions of a sectorial operator is solved in terms of its linear-fractional transformation. Some complements to the J. von Neumann inequality is obtained also.
