Honeycombs and sums of hermitian matrices
WebA Hermitian matrix is a matrix that is equal to its conjugate transpose. Mathematically, a Hermitian matrix is defined as A square matrix A = [a ij] n × n such that A* = A, where A* is the conjugate transpose of A; that is, if for every a ij ∊ A, a i j ― = a i j (1≤ i, j ≤ n), then A is called a Hermitian Matrix.

We give a complete determination of these facets; there is one for each triple of Grassmannian Schubert cycles intersecting in a
WebThe sum or difference of any two Hermitian matrices is Hermitian. Actually, a linear combination of finite number of self-adjoint matrices is a Hermitian matrix. The inverse of an invertible Hermitian matrix is Hermitian as well. The product of two self-adjoint matrices A and B is Hermitian if and only if \( {\bf A}{\bf WebExplore 2 research articles published by the author Jean-Bernard Zuber from Centre national de la recherche scientifique in the year 2024.
