Inverse eigenvalue problems concern the reconstruction of a matrix from prescribed spectral characteristics. Central to this area is the question of existence and uniqueness: given a set of ...
The study of nonlinear eigenvalue problems (NEPs) has matured into a vibrant field at the intersection of numerical analysis, operator theory and applied mathematics. In contrast to the classical ...
research. Here are a few of them. 1) Decomposition of quantum gates. We try to decompose a unitary matrix as the product of simple unitary matrices so that they can be easily implemented. One may see ...
