Adjacency Preserving Maps on Hermitian Matrices

WitrynaI’d like to implement hermitian adjacency matrix and some associated functions. Hermitian adjacency matrix has been proposed in Liu & Li (2015) and these days the matrix is used by various methods, especially spectral clustering algorithms for digraph. e.g. Cucuringu, Li, Sun, & Zanetti (2024), Laenen & Sun (2024) I'd like to get these … WitrynaA consequence of this definition is that every real symmetric matrix is Hermitian. Example 10.3.3. If A = 2 3-3 i 3 + 3 i 5 then A * = 2 3-3 i 3 + 3 i 5 = A, and hence A is Hermitian. As we had with symmetric matrices, Hermitian matrices have three important properties that combine to give the spectral theorem in the complex setting ... WitrynaSince H(t)is a unitary matrix,if PST happens in the graph from u to v,then the entries in the u-th row and the entries in the v-th column of H(t)are all zero except for the(u,v)-th entry.That is,the probability starting from u to v is absolutely 1,which is an idea model of state transferring.In other words,quantum walks on finite graphs provide ... facebook marketplace curtains

Witrynanotation and deﬁnitions. We order the eigenvalues of an n × n Hermitian matrix A as µ1 (A) ≥ ... ≥ µ n (A). Suppose 1 < k < n and let A and B be Hermitian matrices of size n × n and k × k. As usual, we say that the eigenvalues of A and B are interlaced, if µ i (A) ≥ µ i (B) ≥ µ n−k+i (A) for all i ∈ [k]. The interlacing is ... WitrynaHence if A is both unitary and Hermitian, we have A = A − 1 (and A is unitary). As for theoretical uses, the group S U n ± ( C) is generated by such matrices for every n, …
