摘要 | Let D be a division ring which possesses an involution a --> (a) over bar. Assume that F = {a is an element of D\a = (a) over bar} is a proper subfield of D and is contained in the center of D. It is pointed out that if D is of characteristic not two, D is either a separable quadratic extension of F or a division ring of generalized quaternions over F and that if D is of characteristic two, D is a separable quadratic extension of F. Thus the trace map Tr: D --> F, a --> a + (a) over bar is always surjective, which is formerly posed as an assumption in the fundamental theorem of n x n hermitian matrices over D when n greater than or equal to 3 and now can be deleted. When D is a field, the fundamental theorem of 2 x 2 hermitian matrices over D has already been proved. This paper proves the fundamental theorem of 2 x 2 hermitian matrices over any division ring of generalized quaternions of characteristic not two. |
