Regularity points and Jensen measures for R(X) (2016)
Journal Article
Feinstein, J., & Yang, H. (in press). Regularity points and Jensen measures for R(X). Studia Mathematica, 235(1), https://doi.org/10.4064/sm8351-7-2016

We discuss two types of `regularity point', points of continuity and R-points for Banach function algebras, which were introduced by the first author and Somerset in (2000). We show that, even for the natural uniform algebras R(X) (for compact plane... Read More about Regularity points and Jensen measures for R(X).

The chain rule for F-differentiation (2016)
Journal Article
Chaobankoh, T., Feinstein, J., & Morley, S. (2016). The chain rule for F-differentiation

Let X be a perfect, compact subset of the complex plane, and let D (1)(X) denote the (complex) algebra of continuously complex-differentiable functions on X. Then D(1)(X) is a normed algebra of functions but, in some cases, fails to be a Banach funct... Read More about The chain rule for F-differentiation.

Abstract Swiss cheese space and classicalisation of Swiss cheeses (2016)
Journal Article
Feinstein, J., Morley, S., & Yang, H. (2016). Abstract Swiss cheese space and classicalisation of Swiss cheeses. Journal of Mathematical Analysis and Applications, 438(1), 119-141. https://doi.org/10.1016/j.jmaa.2016.02.004

Swiss cheese sets are compact subsets of the complex plane obtained by deleting a sequence of open disks from a closed disk. Such sets have provided numerous counterexamples in the theory of uniform algebras. In this paper, we introduce a topological...
