Longyun Ding · Journal of Nankai University · 2002
In this paper, the concept of pseudo-Euclidean ring is introduced and some basic properties of pseudo-Euclidean ring are given. In theorem 1, the main theorem of this paper, it is proved that the matrix ring with entries in a pseudo-Euclidean ring is also a pseudo-Euclidean ring. In the end, another definition of pseudo-Eclidean ring is given, in which no norm δ appeared.$$$$
