Boundaries for Gelfand transform images of Banach algebras of holomorphic functions
Yun Sung Choi, Mingu Jung
Let be a Banach algebra of bounded holomorphic functions on the open unit ball of a complex Banach space . Considering the Gelfand transform image $\widehat{…
The spectra of Banach algebras of holomorphic functions on polydisk type domains
Yun Sung Choi, Mingu Jung, Manuel Maestre
R.M. Aron et al. proved that the Cluster Value Theorem in the infinite dimensional Banach space setting holds for the Banach algebra . On the other ha…
On quasi norm attaining operators between Banach spaces
Geunsu Choi, Yun Sung Choi, Mingu Jung +1
We introduce a weakened notion of norm attainment for bounded linear operators between Banach spaces which we call \emph{quasi norm attaining operators}. An operator $T\colon X \lo…
Emerging notions of norm attainment for Lipschitz maps between Banach spaces
Geunsu Choi, Yun Sung Choi, Miguel Martin
We classify several notions of norm attaining Lipschitz maps which were introduced previously, and present the relations among them in order to verify proper inclusions. We also an…
The Bishop-Phelps-Bollobás property and absolute sums
Yun Sung Choi, Sheldon Dantas, Mingu Jung +1
In this paper we study conditions assuring that the Bishop-Phelps-Bollobás property (BPBp, for short) is inherited by absolute summands of the range space or of the domain space. C…
The Bishop-Phelps-Bollobás properties in complex Hilbert spaces
Yun Sung Choi, Sheldon Dantas, Mingu Jung
In this paper we consider a stronger property than the Bishop-Phelps-Bollobás property for various classes of operators on a complex Hilbert space. The Bishop-Phelps-Bollobás {\it…
