On Birkhoff angles in normed spaces
Hendra Gunawan, Muhamad Jamaludin, Mas Daffa Pratamadirdja
Associated to Birkhoff orthogonality, we study Birkhoff angles in a normed space and present some of their basic properties. We also discuss how to decide whether an angle is more…
On geometric constants for discrete Morrey spaces
Adam Adam, Hendra Gunawan
In this note we prove that the -th Von Neumann-Jordan constant and the -th James constant for discrete Morrey spaces where are both equal to .…
A Note on Inclusions of Discrete Morrey Spaces
Hendra Gunawan, Denny Ivanal Hakim, Mochammad Idris
We give a necessary condition for inclusion relations between discrete Morrey spaces which can be seen as a complement of the results in \cite{GKS,HS2}. We also prove another inclu…
Fefferman's Inequality and Applications in Elliptic Partial Differential Equations
Nicky K. Tumalun, Denny I. Hakim, Hendra Gunawan
In this paper we prove Fefferman's inequalities associated to potentials belonging to a generalized Morrey space or a Stummel class . Our results gen…
