Hybrid preconditioning for iterative diagonalization of ill-conditioned generalized eigenvalue problems in electronic structure calculations
Yunfeng Cai, Zhaojun Bai, John E. Pask +1
The iterative diagonalization of a sequence of large ill-conditioned generalized eigenvalue problems is a computational bottleneck in quantum mechanical methods employing a nonorth…

Gradient bounds for Wachspress coordinates on polytopes
Michael Floater, Andrew Gillette, N. Sukumar
We derive upper and lower bounds on the gradients of Wachspress coordinates defined over any simple convex d-dimensional polytope P. The bounds are in terms of a single geometric q…
