Principal submatrices III: Linear inequalities
, 1968 Let H be an n x n Hermitian matrix with eigenvalues [Equation not included]. Let H(i|i) denote the principal submatrix of H obtained by deleting row i from H. Let [Equation not included] be the eigenvalues of H(i|i). The famous Cauchy inequalities assert

On Positive Partial Transpose Matrices
, 2020 This paper mainly focuses on the class of $2 \times 2$ block PPT matrices. The relationship between PPT matrices and the norm inequalities is further explored. Some properties of a non-PPT matrix in terms of its eigenvalues are investigated.

Intersection bounds: estimation and inference [PDF]
, 2009 We develop a practical and novel method for inference on intersection bounds, namely bounds defined by either the infimum or supremum of a parametric or nonparametric function, or equivalently, the value of a linear programming problem with a potentially

Scientific ReportsAbstract This paper presents design and development of an optimal robust PI controller based on linear matrix inequalities for a typical industrial process control system. In this method, the design problem has been transformed into a state feedback controller design problem for an augmented uncertainty MIMO system.
