. A commuting tuple of n -operators ( S 1 , . . . , S n − 1 , P ) on a Hilbert space H is called a Γ n -contraction if the closed symmetrized polydisc is a spectral set. Also a commuting triple of operators ( A, B, P ) for which the closed tetrablock E is a spectral set is called an E -contraction, where To every Γ n -contraction, there is a unique operator tuple ( A 1 , . . . , A n − 1 ), deﬁned on Ran D P , such that This is called the fundamental operator tuple (or in short the F O -tuple…

This note finds a necessary condition and a sufficient condition under which there exist a Hilbert space H and a Γn-contraction (S1, S1, Sn−1, P) on H such that (A1, A1, An−1) becomes the FO-tuple of (S 1, S 1, Sn − 1, P ).

For n ≥ 2, the symmetrized polydisc is the following family of polynomially convex domains: Gn = {( ∑ 1≤i≤n zi, ∑ 1≤i< j≤n ziz j, . . . , n ∏ i=1 zi ) : |zi|< 1, i = 1, . . . ,n } . A distinguished…

The tetrablock, roughly speaking, is the set of all linear fractional maps that map the open unit disc to itself. A formal definition of this inhomogeneous domain is given below. This paper considers…

A tuple of commuting operators $$(S_1,\dots ,S_{n-1},P)$$(S1,⋯,Sn-1,P) for which the closed symmetrized polydisc $$\Gamma _n$$Γn is a spectral set is called a $$\Gamma _n$$Γn-contraction. We show…
