Backward Error Analysis for Eigenproblems Involving Conjugate Symplectic Matrices

, 2015
Conjugate symplectic eigenvalue problems arise in solving discrete linearquadratic optimal control problems and discrete algebraic Riccati equations. In this article, backward errors of approximate pairs of conjugate symplectic matrices are obtained from

A Well-Conditioned Hierarchical Basis for Triangular H(curl)-Conforming Elements

, 2011
We construct a well-conditioned hierarchical basis for triangular H(curl)conforming elements with selected orthogonality. The basis functions are grouped into edge and interior functions, and the later is further grouped into normal and bubble functions.
