Plemmons (1938-2026) Robert J. Plemmons passed away on February 6, 2026, at the age of 87. Born in Old Fort, North Carolina in 1938, he earned his B.S. in mathematics from Wake Forest University in 1962 and his Ph.D. from Auburn University in 1965, working primarily with Emilie Haynesworth. Bob held positions at the National Security Agency and The Martin Company, as well as academic appointments at the University of Mississippi, the University of Tennessee (where he met his mentor Alston Householder), and North Carolina State University. In 1990, he returned to Wake Forest University as the Z. Smith Reynolds Professor of Mathematics and Computer Science. He retired from teaching in 2013 but remained active in research thereafter. Bob's research career began in semigroup theory and finite algebraic systems, with his first publication appearing in 1965. In the early 1970s, he shifted toward matrix theory, making foundational contributions to generalized inverses, nonnegative matrices, and M-matrices. His work significantly advanced the numerical analysis of singular and rectangular linear systems, extending classical results for nonsingular problems. A major highlight of this period was his collaboration with Avi Berman, which led to the influential 1979 book Nonnegative Matrices in the Mathematical Sciences. Widely regarded as a cornerstone of the field, the book was republished by SIAM in 1994 as a Classic in Applied Mathematics. In later years, Bob contributed extensively to large sparse least squares problems, Markov chains, matrix factorizations, and, eventually, to applications in signal and image processing. His work encompassed recursive least squares, FFT-based preconditioning, and adaptive optics for ground-based telescope imaging. Even in retirement, he continued this research with support from the Air Force Office of Scientific Research and the National Aeronautics and Space Administration, focusing on space situational awareness and remote sensing. Bob's work was recognized by many awards, including being named a SIAM Fellow in 2013. Bob was also deeply committed to service, acting as a journal editor, conference organizer, and advocate for the mathematical sciences. Outside academia, Bob was a gifted athlete who played baseball in the Baltimore Orioles farm system, an avid fisherman and gardener, and a licensed pilot. Known especially for his kindness and generosity, Bob Plemmons will be fondly remembered and greatly missed. A more extensive biography of Bob's early career was published in 2000 issue of Linear Algebra and its Applications in celebration of Bob's 60th birthday; https://www.sciencedirect.com/journal/linear-algebra-and-its-applications/vol/316/issue/1 See also the memorial at https://memoritree.com/memorial/robert-james-plemmons Raymond Chan, Lingnan University James Nagy, Emory University Paul Paúca, Wake Forest University Sudhakar Prasad, University of Minnesota and University of New Mexico ------------------------------------------------------- From: Scott MacLachlan smaclachlan@mun.ca Date: February 06, 2026 Subject: 2026 Colorado Conference on Iterative and Multigrid Methods, June 2026 2026 Colorado Conference on Iterative and Multigrid Methods Sunday June 21 - Friday June 26, 2026 Boulder, Colorado, USA The Copper Mountain Conference on Multigrid Methods was founded in 1983 and held every two years (odd years) since then. In 1990, the Copper Mountain Conference on Iterative Methods was formed as a companion conference to be held in even years. Together, they are widely regarded as premier international conferences on iterative and multigrid methods.
