Least-Squares Spectral Methods for ODE Eigenvalue Problems [PDF]
SIAM Journal of Scientific Computing, 2022 We develop spectral methods for ODEs and operator eigenvalue problems that are based on a least-squares formulation of the problem. The key tool is a method for rectangular generalized eigenvalue problems, which we extend to quasimatrices and objects combining quasimatrices and matrices.

Controllable graphs with least eigenvalue at least -2 [PDF]
Applicable Analysis and Discrete Mathematics, 2011 Connected graphs whose eigenvalues are distinct and main are called controllable graphs in view of certain applications in control theory. We give some general characterizations of the controllable graphs whose least eigenvalue is bounded from below by - 2; in particular, we determine all the controllable exceptional graphs.

The Least Eigenvalue of Graphs whose Complements Are Uni- cyclic
Discussiones Mathematicae Graph Theory, 2015 A graph in a certain graph class is called minimizing if the least eigenvalue of its adjacency matrix attains the minimum among all graphs in that class. Bell et al.

Approximation of the Maxwell eigenvalue problem in a least-squares setting
Computers and Mathematics With Applications, 2023 We discuss the approximation of the eigensolutions associated with the Maxwell eigenvalues problem in the framework of least-squares finite elements. We write the Maxwell curl curl equation as a system of two first order equation and design a novel least-squares formulation whose minimum is attained at the solution of the system.
