Web23 jul. 2024 · I found this interesting SDP exercise problem on minimizing the second largest eigenvalue of A ( x) = A 0 + ∑ i = 1 n x i A i where A 0, A 1, …, A n are given real symmetric matrices. The given hint says this can be reformulated as an SDP with a rank- 1 constraint. I tried to solve this by following this similar thread. Web10 apr. 2024 · To ensure that I L − ρ m A is invertible, we require that that ρ m (j) ∈ [0, λ m a x] where λ m a x refers to the largest eigenvalue of A (Jin et al., 2005). While this specification for the precision matrix of Ω m ( j ) may be somewhat opaque at first sight, an application of Brook’s lemma as reviewed in Banerjee et al. (2014) shows that this … Web3 Answers. The sum of the absolute value of the eigenvalues is the same (since the matrix is real and symmetric) as the sum of the singular values.
