Such a phenomenon is now often referred to as the Reproducing Kernel Thesis (RKT). In this paper we prove RKT for differences of composition operators acting on the Hardy-Hilbert space over the ball. We also obtain a modified Carleson characterization for the difference related to RKT when the composition operators are bounded. 2026-12-01T00:00:00Z Schatten Class Difference of Composition Operators on the Bergman Space Choe, Boo Rim Choi, Koeun Koo, Hyungwoon Park, Inyoung https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/212889 2026-06-01T00:00:23Z 2026-05-01T00:00:00Z Title: Schatten Class Difference of Composition Operators on the Bergman Space Authors: Choe, Boo Rim; Choi, Koeun; Koo, Hyungwoon; Park, Inyoung Abstract: We investigate the Schatten class membership of the difference of composition operators on the standard weighted Hilbert-Bergman space over the unit disk. Our main result is to characterize Schatten p-class differences of composition operators for the range p >= 2 and to provide a sufficient condition for the range p < 2. Our characterization for p >= 2 extends the known characterization for Hilbert-Schmidt differences. Our approach employs a discretization technique involving lattices and localized averaging over pseudohyperbolic disks. However, such an approach do not seem to work well for the range p < 2 and whether the sufficient condition for p < 2 is also necessary remains open. 2026-05-01T00:00:00Z 교량 유지관리를 위한 AR기술과 교량정보 매칭 기법 제안 탁문호 https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/214227 2026-07-20T20:03:53Z 2025-11-14T00:00:00Z Title: 교량 유지관리를 위한 AR기술과 교량정보 매칭 기법 제안 Authors: 탁문호 2025-11-14T00:00:00Z 교량 3차원 AR 점검 플랫폼 개발 및 실증 연구(제1차) 탁문호 https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/213459 2026-07-18T00:13:04Z 2025-11-01T00:00:00Z Title: 교량 3차원 AR 점검 플랫폼 개발 및 실증 연구(제1차) Authors: 탁문호 2025-11-01T00:00:00Z
