摘要：
The concept of Lie regular elements and Lie regular units was defined and studied by Kanwar, Sharma, and Yadav in Comm. Algebra, 40, No. 4, 1304-1315 (2012). We introduce Jordan regular elements and Jordan regular units. It is proved that the order of the set of Jordan regular units in M(2, Z(2n)) is equal to a half of the order of U(M(2, Z(2n))). Further, we show that the group ring KG of a group G over a field K of characteristic 2 has no Jordan regular units.
