Varga (1928-2022) Richard S. Varga, a giant of our community, died peacefully in the early hours of February 25, 2022. He was 93. Richard made his mark in the profession in multiple ways across several areas: Matrix Analysis, Numerical Methods, Approximation Theory, and more. His first book, Iterative Matrix Analysis, completed when he was 32 years old became a classic. He published a total of seven books, over 230 research papers, directed 25 PhD dissertations, and mentored many younger colleagues. He received many honors and awards, including a senior von Humboldt prize, the Hans Schneider prize, two honorary degrees (Karsruhe and Lille), and becoming a SIAM Fellow and an AMS Fellow. But these numbers are only part of the story. He was a gentleman with a sense of humor, and a generous man. He serviced the community in many ways. He was editor-in-chief of Numerische Mathematik for fourteen years, co-founding editor of ETNA, the Electronic Transactions of Numerical Analysis, serving as co-editor-in-chief for sixteen years, and editor of many important journals in Linear Algebra, Numerical Analysis, and Approximation Theory. Many of us have been inspired by his work and his service ethic. We honor his career and his life. C. Garland, V. Mehrmann, L. Reichel, D.B.

Many techniques have been developed to solve such systems but a number of challenges remain, and research in this field continues to be very active. The course will describe some of the applications where these systems arise and offer a panoramic view of the best solution methods available, up to recent advances. Theoretical foundations will also be addressed. Topics will include: A brief introduction to Krylov subspace methods and preconditioning; Spectral properties of saddle-point matrices; Saddle-point problems arising from finite element discretizations of incompressible flow problems and elliptic PDEs; PDE-constrained optimization problems; Solution of saddle-point problems arising in constrained optimization; Approximate Schur complement and augmented Lagrangian techniques; Constraint preconditioning; Spectral analysis of preconditioned matrices. Reading material will be distributed to the participants, who are expected to take an active role in the learning process. Each participant is required to attend both mornings and afternoon lectures for the entire duration of the course (40hrs). Applications can be submitted exclusively online, on the SMI website: https://www.smi-math.unipr.it/cortona/30/. Application window: 1 March 2022 - April 15, 2022 A selection committee will meet shortly afterward and all accepted applicants will be notified of the result in due time.

The position is part of the research project CUQI, Computational Uncertainty Quantification for Inverse problems (www.compute.dtu.dk/english/cuqi). This position focuses on computational aspects of uncertainty quanti- fication (UQ) for inverse problems formulated in terms of PDEs, with applications in, e.g., inverse scattering problems and problems in electrical impedance tomography. For such problems, standard sampling methods are computationally too expensive to work in practice, and therefore alternatives must be found, e.g., via direct inversion formulas or surrogate models. The goal of the project is to develop and evaluate numerical UQ tools and best practices suited to these inverse problems. The project relies on a combination of theory development and numerical computations. Experience with inverse problems or Bayesian inference will be a plus. For more details and to apply: tinyurl.com/UQPHD The applicant will work in a team of PhD students, postdocs and faculty members in the Section for Scientific Computing, and must contribute with research towards the overall goals of the CUQI project. Applicants are expected to give limited contributions to teaching and training activities as well as supervision of students. The deadline of applications is March 31, 2022 at 23:59 (Danish time). ------------------------------------------------------- From: Heike Sill [log in to unmask] Date: February 22, 2022 Subject: PhD Position, Weakly Coupled Minigrids, WIAS, Germany WIAS invites applications for a PhD student position (f/m/d) (Ref. 22/04) in the Research Group "Nonlinear Optimization and Inverse Problems" (Head: Prof. Dr. D.
