標題: | A note on the right-left symmetry of a R b R = (a + b) R in rings | 作者: | Lee T.-K. TSIU-KWEN LEE |
公開日期: | 2021 | 來源出版物: | Journal of Algebra and its Applications | 摘要: | We give an example to show that, for nonunital rings R, the direct sum aR ± bR = (a + b)R with a + b regular has no in general right-left symmetry. It is then proved that the right-left symmetry actually holds in a left and right faithful ring. ? 2022 World Scientific Publishing Company. |
