The isometric dilation of two parameter semigroup T(n) = T1n1 T2n2, where n = (n1, n2) Î Z2+, for a commutative system {T1, T2} of linear bounded operators, one of which is a contraction, ||T1|| ≤ 1, is constructed. The building of the dilation is based on characteristic qualities of the com- mutative isometric expansion 01-0192e.gif which was given in the previous work by the author [8]. The isometric dilations U(n) and 01-0192e1.gif (n) of the semigroups T(n) and T*(n) are shown to be unitarily linked.
