Results on Banach E*-algebras and preC*-algebras which are E*-algebras are also included.As applications we give a characterization of discrete locally finite groups via E*algebras and answer Kurosh's problem in the affirmative in the case of the convolution *-algebras of compactly supported continuous functions on an arbitrary locally compact group. true 2020 true true true false true false NONE 2026-04-07 false 3 1 3 3 0 3 3 3 3 3 3 3 3 3 0 0 3 3 3 3 0 1 1 Folyóiratcikk Journal Article 24 3 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 2022 0 1 1 1 1 2023 0 2 2 2 2 Q1 false false false false 2021-01-14T12:59:10.421+0000 Alkalmazott Kvantitatív Módszertan Tanszék (BGE / PSZK);
