Question 0.5. (Centers) Consider the group G is the invertible diagonal matrices. [Hint: each central element must commute with the elements of the form 1Eii where 1 is the identity matrix and Ejj is the matrix with 0's everywhere except a 1 in the ith GLT (R) of invertible n xn matrices. Show that Z(GLn (R)) row and jth column. Why is this element in GL, (R)?]
