For real marices, complexλ's andx's come in "conjugate pairs": λ=a+ibandλ¯=a−ib: IfAx=λxthenAx¯=λ¯x¯. EigenvaluesversusPivots The number of positive eigenvalues ofS=S⊤equals the number of postive pivots. All Symmetric Matrices are Diagonalizable. ...
The matrix A is said to be diagonalizable. The diagonal elements of A represent the eigenvalues of the symmetric matrix A. Note that for a symmetric matrix QT = Q- 1. Hence, in general, for a symmetric square matrix we may write (3.34)A=QΛQ−1orAQ=QΛ as long as A has n ind...
where D is the diagonal matrix D=200030006 with the eigenvalues of A on the diagonal. In other words, A is diagonalizable. Let’s go one step further and build a matrix, P, whose columns are those of X converted to a unit vector. Do this by dividing each column vector by its length...

We show that a complex m-by-n matrix A can be factored as A=PΛQT , where P and Q are complex orthogonal matrices and Λ=[λ ij ] is an m-by-n generalized diagonal matrix (λ ij =0 if i ≠ j), if and only if ATA is diagonalizable and ran... D Choudhury,RA Horn - 《...
if a is diagonalizable over f and has only two distinct eigenvalues 1 and -1, show that a^2=in, where in is an n n identity matrix. Let A be an n x n matrix such that A^{4} = I_n and let M = A^3+A^2 + A + I_n. If |M| not equal to 0, show that A...
We call ({{\mathfrak {g}}},\tau ,C) non-compactly causal (ncc) if C is hyperbolic in the sense that, for x \in C^\circ , the operator \mathop {\textrm{ad}}\nolimits x is diagonalizable. As explained in detail in [41], Euler elements in reductive Lie algebras {{\mathfrak ...
