*n*finite sequence of real numbers $$\beta \equiv \beta ^{(2n)}= \{ \beta _{00},\beta _{10},$$ β ≡ β ( 2 n ) = { β 00 , β 10 , $$\beta _{01},\ldots , \beta _{2n,0}, \beta _{2n-1,1},\ldots , \beta _{1,2n-1},\beta _{0,2n} \}$$ β 01 , … , β 2 n , 0 , β 2 n - 1 , 1 , … , β 1 , 2 n - 1 , β 0 , 2 n } to have a representing measure $$\mu...

*p*-th power of each weight or forming the Aluthge transform. We determine in a number of cases whether the resulting shift is subnormal, and, if it is, find a concrete representation of the associated Berger measure, directly for finitely atomic measures, and using both Laplace transform and Fourier transform...

*m*-tuples, and use it to analyze hypercontractivity and hyperexpansivity in several variables. These two notions encompass (joint) hyponormality and subnormality, as well as toral and spherical isometric-ness; for instance, the...
