The first k columns take the form AB1, ,ABk, but since B1, ,Bkare eigenvectors corresponding to 1, the first k columns are B1, ,Bk. The problem I am running into is that V is not orthogonal, ie $V*V^T$ does not equal the identity matrix( I am doing all of this in $R$). Since the columns of B along with X are orthogonal, XTBj= X Bj = 0 for any column Bj in B, and so XTB = 0, as well as BTX = (XTB)T = 0. Therefore the spectral decomposition of can be written as.
