The ▫$n$▫-insertive subgroups of unitsDolžan, DavidNaj bo ▫$R$▫ končni kolobar, ▫$G$▫ njegova grupa enot, ▫$J$▫ pa Jacobsonov radikal. Naj bo še ▫$n$▫ poljubno celo število. Dokažemo, da je ▫$R$▫ ▫$n$▫-vstavljivi kolobar natanko tedaj, ko je ▫$G$▫ ... ▫$n$▫-vstavljiva grupa in pokažemo, da je vsak ▫$n$▫-vstavljivi končni kolobar direktna vsota lokalnih kolobarjev. Dokažemo tudi, da je v primeru, ko je ▫$n$▫ enota, lokalni kolobar ▫$R$▫ ▫$n$▫-vstavljiv natanko tedaj, ko je njegova Jacobsonova grupa ▫$1+J$▫ ▫$n$▫-vstavljiva in najdemo primer, da to ne drži, če ▫$n$▫ ni enota.Source: Bulletin of the Australian Mathematical Society. - ISSN 0004-9727 (Vol. 75, no. 1, 2007, str. 23-26)Type of material - article, component partPublish date - 2007Language - englishCOBISS.SI-ID - 14430041
