Majorization in some symplectic weak supermajorizations
Shaowu Huang, Hemant K. Mishra
Symplectic eigenvalues are known to satisfy analogs of several classic eigenvalue inequalities. Of these is a set of weak supermajorization relations concerning symplectic eigenval…

Equality in some symplectic eigenvalue inequalities
Hemant K. Mishra
In the last decade, numerous works have investigated several properties of symplectic eigenvalues. Remarkably, the results on symplectic eigenvalues have been found to be analogous…
