Maximum eigenvalue of a+b

Web27 nov. 2016 · Eigenvalues of a positive definite real symmetric matrix are all positive. Also, if eigenvalues of real symmetric matrix are positive, it is positive definite. Let A be a n × n Hermitian matrix. As with many other variational results on eigenvalues, one considers the Rayleigh–Ritz quotient RA : C \ {0} → R defined by where (⋅, ⋅) denotes the Euclidean inner product on C . Clearly, the Rayleigh quotient of an eigenvector is its associated eigenvalue. Equivalently, the Rayleigh–Ritz quotient can be replaced by
