In particular, the uniqueness of the Lebesgue decomposition of positive functionals over the L-1-algebras of locally compact groups provides a new characterization of Moore groups. true 2024 true true true false true false NONE 2026-04-07 false 1 0 1 1 0 1 1 1 1 1 1 1 1 1 0 0 1 1 1 1 0 5 5 Folyóiratcikk Journal Article 24 1 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2024 0 1 1 1 1 Q1 false false false false 2024-07-11T10:40:33.821+0000 Differenciálegyenletek Tanszék (BME / TTK / MI) 2 22 1 2 0 true Language 10002 /api/language/10002 English Angol English true 2 true PersonAuthorship 116160256 /api/authorship/116160256 Szucs, Zsolt ✉ [Szűcs, Zsolt (matematika), author] Department of Differential Equations (BUTE / FNS / IM) 1 0.5 true false true Author 10029438 /api/author/10029438 Zsolt Szűcs (matematika) Szűcs Zsolt true 10029438 true Szucs Zsolt true false false AuthorshipType 1 /api/authorshiptype/1 Author 0 true 0 true false true PersonAuthorship 116160257 /api/authorship/116160257 Takacs, Balazs [Takács, Balázs (funkcionálanalízis), author] 2 0.5 false true false Author 10066279 /api/author/10066279 Balázs Takács (funkcionálanalízis) Takács Balázs true true Takacs Balazs true false false AuthorshipType 1 /api/authorshiptype/1 Author 0 true 0 true false true PublicationIdentifier 25997082 /api/publicationidentifier/25997082 DOI: 10.7900/jot.2022jan28.2395 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.7900/jot.2022jan28.2395 https://doi.org/10.7900/jot.2022jan28.2395 false true PublicationIdentifier 25997083 /api/publicationidentifier/25997083 WoS: 001185553600008 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001185553600008 https://www.webofscience.com/wos/woscc/full-record/001185553600008 false true PublicationIdentifier 29258584 /api/publicationidentifier/29258584 Scopus: 105002180398 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105002180398 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105002180398 false true PublicationIdentifier 25997237 /api/publicationidentifier/25997237 Other URL: http://www.mathjournals.org/jot/2024-091-001/2024-091-001-003.html PlainSource 40 /api/publicationsource/40 Other URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true http://www.mathjournals.org/jot/2024-091-001/2024-091-001-003.html http://www.mathjournals.org/jot/2024-091-001/2024-091-001-003.html false true Classification 10003 /api/classification/10003 Mathematics true true Keyword 1083123 /api/keyword/1083123 ALGEBRAS true 1083123 true Keyword 1180317 /api/keyword/1180317 Lebesgue decomposition true 1180317 true Keyword 1354856 /api/keyword/1354856 Irreducible representation true 1354856 true Keyword 1823726 /api/keyword/1823726 positive functional true true Keyword 3369858 /api/keyword/3369858 enveloping von Neumann algebra true true Keyword 3369859 /api/keyword/3369859 Moore group true true SjrRating 11437785 /api/sjrrating/11437785 sjr:Q1 (2024) Scopus - Algebra and Number Theory JOURNAL OF OPERATOR THEORY 0379-4024 1841-7744 31 0.24 journal RatingType 10002 /api/ratingtype/10002 sjr sjr true true ClassificationExternal 2602 /api/classificationexternal/2602 Scopus - Algebra and Number Theory true 2602 true Q1 DIRECT true true Reference 51873029 /api/reference/51873029 1.
