TY - JOUR AU - 허재성 DA - 2018/12 PY - 2018 UR - http://www.doiserbia.nb.rs/Article.aspx?ID=0354-51801817001A#.XWTDK2Z7mdI UR - https://repository.hanyang.ac.kr/handle/20.500.11754/120872 AB - In this paper, we introduce a notion of the J-kernel of a bounded linear operator on a Krein space and study the J-Fredholm theory for Krein space operators. Using J-Fredholm theory, we discuss when (a-)J-Weyl's theorem or (a-)J-Browder's theorem holds for bounded linear operators on a Krein space instead of a Hilbert space.
