On the quality of complementary bounds for eigenvalues
L. Boulton, A. Hobiny
A concrete formulation of the Lehmann-Maehly-Goerisch method for semi-definite self-adjoint operators with compact resolvent is considered. Precise rates of convergence are determi…

On the convergence of the quadratic method
Lyonell Boulton, Aatef Hobiny
The convergence of the so-called quadratic method for computing eigenvalue enclosures of general self-adjoint operators is examined. Explicit asymptotic bounds for convergence to i…
