Boundedness of composition operator in Orlicz-Morrey spaces
Masahiro Ikeda, Isao Ishikawa, Ryota Kawasumi
In this paper, we investigate necessary and sufficient conditions on the boundedness of composition operators on the Orlicz-Morrey spaces. The results of boundedness include Lebesg…
Boundedness of composition operators on higher order Besov spaces in one dimension
Masahiro Ikeda, Isao Ishikawa, Koichi Taniguchi
This paper aims to characterize boundedness of composition operators on Besov spaces of higher order derivatives on the one-dimensional Euclidean space. In co…
Global universality of the two-layer neural network with the -rectified linear unit
N. Hatano, M. Ikeda, I. Ishikawa +1
This paper concerns the universality of the two-layer neural network with the -rectified linear unit activation function with with a suitable norm without any res…
Bounded composition operators on functional quasi-Banach spaces and stability of dynamical systems
Isao Ishikawa
In this paper, we investigate the boundedness of composition operators defined on a quasi-Banach space continuously included in the space of smooth functions on a manifold. We prov…
Boundedness of composition operators on Morrey spaces and weak Morrey spaces
Naoya Hatano, Masahiro Ikeda, Isao Ishikawa +1
In this study, we investigate the boundedness of composition operators acting on Morrey spaces and weak Morrey spaces. The primary aim of this study is to investigate a necessary a…
Composition operators on reproducing kernel Hilbert spaces with analytic positive definite functions
Masahiro Ikeda, Isao Ishikawa, Yoshihiro Sawano
In this paper, we specify what functions induce the bounded composition operators on a reproducing kernel Hilbert space (RKHS) associated with an analytic positive definite functio…
