Models of holomorphic functions on the symmetrized skew bidisc

Connor Evans, Zinaida A. Lykova, N. J. Young

The purpose of this paper is to develop the theory of holomorphic functions with modulus bounded by on the symmetrized skew bidisc \[ \mathbb{G}_{r} \stackrel{\rm def}{=} \Big\…

Boundary behavior of functions in the Schur-Agler class of the polydisc

Jim Agler, Connor Evans, Zinaida Lykova +1

We describe a generalization of the notion of a Hilbert space model of a function in the Schur-Agler class of the polydisc. This generalization is well adapted to the investiga…

Function theory on the annulus in the dp-norm

Jim Agler, Zinaida Lykova, N. J. Young

In this paper we shall use realization theory to prove new results about a class of holomorphic functions on an annulus \[R_δ\stackrel{\rm def}{=} \{z \in \mathbb{C}: δ<|z|<1\},\]…

Function theory in the bfd-norm on an elliptical region

Jim Agler, Zinaida Lykova, Nicholas Young

Let be the open region in the complex plane bounded by an ellipse. The B. and F. Delyon norm on the space of holomorphic functions…

Rational tetra-inner functions and the special variety of the tetrablock

Omar M. O. Alsalhi, Zinaida A. Lykova

The set \[ \overline{\mathbb{E}}= \{ x \in {\mathbb{C}}^3: \quad 1-x_1 z - x_2 w + x_3 zw \neq 0 \mbox{ whenever } |z| < 1, |w| < 1 \} \] is called the tetrablock and has intriguin…
