✦ Synopsis


We have found a central polynomial of degree 13 for the (4 \times 4) matrix algebra over a field of characteristic 0 . This result agrees with the conjecture that the minimal degree of such polynomials for (n \times n) matrices is (\left(n^{2}+3 n-2\right) / 2). The polynomial has been obtained by explicitly exhibiting an essentially weak polynomial identity of degree 9 for (4 \times 4) matrices. 1994 Academic Press. Inc

The complex orthogonal group O n acts on the n × n matrices, M n , by restricting the adjoint action of GL n . This action provides us with an action on the ring of complex valued polynomial functions on the n × n matrices, M n . The polynomials of degree d, denoted d M n , form a finite dimensiona
