WitrynaThe complex case is considered to allow unconstrained phase randomization in the transformed domain, hence we define a Hermitian Laplacian matrix that models the graph topology, whose eigenvectors form the basis of a complex graph Fourier transform. We have shown that the Hermitian Laplacian matrix may have negative eigenvalues. Witryna[] The Hermitian conjugate of an operator. Consider that the matrix representation of the operator is given by: and the following two state vectors from the same Hilbert space are given by: (a) Find the result of and . (b) Find the Hermitian conjugates and , and use these to calculate the inner products between the two state vectors and .
