Some new results on the semiduality of small sets of analytic functions

Abstract
Continuing work from [5], we use some normality criteria to show that certain sets of two analytic functions are not semidual. In particular, sets of the form V := {z ↦ 1/(1 - z);φ} where φ is a rational function analytic in the unit disk are studied, and sufficient conditions for V being not semidual are given.
