Hendrik "Henk" Albertus van der Vorst (born 5 May 1944, Venlo)[1] is a Dutch mathematician and Emeritus Professor of Numerical Analysis at Utrecht University.
[6] Henk van der Vorst is a Fellow of Society for Industrial and Applied Mathematics (SIAM).
He has analyzed convergence behavior of the conjugate gradient[12] and Lanczos methods.
He has also developed a number of preconditioners for parallel computers,[13] including truncated Neumann series preconditioner, incomplete twisted factorizations, and the incomplete factorization based on the so-called "vdv" ordering.
He is the author of the book Iterative Krylov Methods for Large Linear systems[14] and one of the authors of the Templates projects for linear problems[15] and eigenproblems.
