Hendrik "Henk" Albertus van der Vorst (born May 5, 1944) is a Dutch mathematician and Emeritus Professor of Numerical Analysis at Utrecht University. According to the Institute for Scientific Information (ISI), his paper〔 〕 on the Bi-CGSTAB method was the most cited paper in the field of mathematics in the 1990s.〔 〕 He is a member of the Royal Netherlands Academy of Arts and Sciences (KNAW) since 2002 and the (Netherlands Academy of Technology and Innovation ).〔 〕 In 2006 he was awarded a knighthood of the Order of the Netherlands Lion. Henk van der Vorst is a Fellow of Society for Industrial and Applied Mathematics (SIAM).〔 (【引用サイトリンク】title=SIAM Fellows: Class of 2009 )〕 His major contributions include preconditioned iterative methods, in particular the ICCG (incomplete Cholesky conjugate gradient) method (developed together with Koos Meijerink), a version of preconditioned conjugate gradient method,〔 〕〔 〕 the Bi-CGSTAB〔 and (together with Kees Vuik) GMRESR〔 〕 Krylov subspace methods and (together with Gerard Sleijpen) the Jacobi-Davidson method〔 〕 for solving ordinary, generalized, and nonlinear eigenproblems. He has analyzed convergence behavior of the conjugate gradient〔 〕 and Lanczos methods. He has also developed a number of preconditioners for parallel computers,〔 〕 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〔 〕 and one of the authors of the Templates projects for linear problems〔 〕 and eigenproblems.〔 〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Henk van der Vorst」の詳細全文を読む スポンサード リンク
