Triangular Matrix Representations and Triangular Matrix Extensions,criterion for a ring with a complete set of triangulating idempotents to be quasi-Baer is provided. A structure theorem for a quasi-Baer ring with a complete set of triangulating idempotents is shown using complete triangular matrix representations. A number of well known results follow as consequenCumbersome 发表于 2025-3-29 05:41:03
Matrix, Polynomial, and Group Ring Extensions,are utilized to do so. It is observed that the Baer property of a ring does not transfer to its ring extensions so readily and that this happens only under special conditions. However, it will be shown that the quasi-Baer property transfers to various matrix and polynomial ring extensions without anExcise 发表于 2025-3-29 09:51:45
