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…

The Lipschitz bounded approximation property for operator ideals
Geunsu Choi, Mingu Jung
In this article, we introduce the Lipschitz bounded approximation property for operator ideals. With this notion, we extend the original work done by Godefroy and Kalton and give s…

The Birkhoff-James orthogonality and norm attainment for multilinear maps
Geunsu Choi, Sun Kwang Kim
Very recently, motivated by the result of Bhatia and Šemrl which characterizes the Birkhoff-James orthogonality of operators on a finite dimensional Hilbert space in terms of norm…
