A formula for the -angle between two subspaces of a normed space
Muhammad Nur, Hendra Gunawan, Oki Neswan
We develop the notion of -angle between two subspaces of a normed space. In particular, we discuss the -angle between a -dimensional subspace and a -dimensional subspac…
Generalized Hölder's inequality on Morrey spaces
Ifronika, Mochammad Idris, Al Azhary Masta +1
The aim of this paper is to present necessary and sufficient conditions for generalized Hölder's inequality on generalized Morrey spaces. We also obtain similar results on weak Mor…
Norm estimates for Bessel-Riesz operators on generalized Morrey spaces
Mochammad Idris, Hendra Gunawan, Eridani
We revisit the properties of Bessel-Riesz operators and refine the proof of the boundedness of these operators on generalized Morrey spaces using Young's inequality. We also obtain…
On Inclusion Properties of Two Versions of Orlicz-Morrey Spaces
Al A. Masta, Hendra Gunawan, Wono Setya-Budhi
There are two versions of Orlicz-Morrey spaces (on ), defined by Nakai in 2004 and by Sawano, Sugano, and Tanaka in 2012. In this paper we discuss the inclusion prope…
Proper inclusions of Morrey spaces
Hendra Gunawan, Denny I. Hakim, Mochammad Idris
In this paper, we prove that the inclusions between Morrey spaces, between weak Morrey spaces, and between a Morrey space and a weak Morrey space are all proper. The proper inclusi…
