A note on numerical radius attaining mappings
Mingu Jung
We prove that if every bounded linear operator (or -homogeneous polynomials) with the compact approximation property attains its numerical radius, then is a finite dimension…
On the strong subdifferentiability of the homogeneous polynomials and (symmetric) tensor products
Sheldon Dantas, Mingu Jung, Martin Mazzitelli +1
In this paper, we study the (uniform) strong subdifferentiability of the norms of the Banach spaces , and $\hat{\…
On the Lipschitz numerical index of Banach spaces
Geunsu Choi, Mingu Jung, Hyung-Joon Tag
We provide some new consequences on the Lipschitz numerical radius and index which were introduced recently. More precisely, we give some renorming results on the Lipschitz numeric…
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{…
Some remarks on the weak maximizing property
Sheldon Dantas, Mingu Jung, Gonzalo Martínez-Cervantes
A pair of Banach spaces is said to have the weak maximizing property (WMP, for short) if for every bounded linear operator from into , the existence of a non-we…
On norm-attainment in (symmetric) tensor products
Sheldon Dantas, Luis C. García-Lirola, Mingu Jung +1
In this paper, we introduce a concept of norm-attainment in the projective symmetric tensor product of a Banach space , which turns out to be natur…
