We survey the quadratic eigenvalue problem, treating its many applications, its
mathematical properties, and a variety of numerical solution techniques. Emphasis is given …

trivial case when l= 1 and Al is positive (or negative) definite). Hence the properties of …

The Handbook of Linear Algebra provides comprehensive coverage of linear algebra
concepts, applications, and computational software packages in an easy-to-use handbook …

Pseudospectra associated with the standard and generalized eigenvalue problems have
been widely investigated in recent years. We extend the usual definitions in two respects, by …

We characterize the operational task of environment-assisted distillation of quantum
coherence under different sets of free operations when only a finite supply of copies of a …

We show that for qubits and qutrits it is always possible to perfectly recover quantum
coherence by performing a measurement only on the environment, whereas for dimension …

We consider the numerical solution of the large scale singular Sylvester equation of the form
AX− XD⊤= E (or AXB⊤− CXD⊤= E), where the spectra Λ (A) and Λ (D)(or, Λ (A− λ C) and Λ …

The pseudospectra of a matrix polynomial P(λ) are sets of complex numbers that are
eigenvalues of matrix polynomials which are near to P(λ); ie, their coefficients are within …

We analyze when an arbitrary matrix pencil is strictly equivalent to a dissipative Hamiltonian
pencil and show that this heavily restricts the spectral properties. In order to relax the …
