WebFor α = 1,2 this gives closed forms for the eigenvalues of the permutation and perfect matching derangement graphs, resolving an open question in algebraic graph theory. A byproduct of the latter is a simple combinatorial formula for the immanants of the matrix J −I where J is the all-ones matrix, which might be of independent interest.
WebThe Eigenvalues of a Hermitian matrix are always real. Let A be a Hermitian matrix such that A* = A and λ be the eigenvalue of A. Let X be the corresponding Eigen vector such that AX = λX where X = [ a 1 + i b 1 a 2 + i b 2... a n + i b n] Then X* will be a conjugate row vector. Multiplying X* on both side of AX = λX we have,
