Jiang Hai-qin · Journal of Taizhou Polytechnical Institute · 2004
The product of such matrixes as =1 and matrix notation of A:P(i,j) and P(i,j(k)) for necessary and sufficient condition of invertible matrix in integral ring is given in this paper , resulting in the solution to invertible matrix in integral ring . In the meantime , the sufficient condition of invertible matrix is presented here.
