A Divide-and-Conquer Method for the Takagi Factorization

Web11 set 2024 · As described here the Takagi factorization of a square symmetric complex matrix $A=VDV^T$ where D is a real nonnegative diagonal matrix, and V is unitary. I'm … Webquantum theory applications—the singular value decomposition and the Autonne-Takagi factorization. In this pedagogical review, each of these diagonalization procedures is per-formed for the most general 2×2 matrices for which the corresponding diagonalization is possible, and explicit analytical results are provided in each of the three cases. WebThe Takagi factorization of a complex symmetric n×nmatrix Acan be written as A= VΣVT, where V is a unitary matrix, VT is the transpose of V and Σ is a diagonal matrix with non-negative diagonal elements. The columns of V are called the Takagi vectors of Aand the diagonal elements of Σ are its Takagi values. Since VT = V¯H, where V ... rudd tax service
