He joined the UIUC Department of Computer Science in 1967 after receiving a BS from Stanford University in 1961, an MS from the University of Texas in 1963, and a PhD from Rice University (all three degrees were in Mathematics). Paul found great joy and success in interdisciplinary work and helped the Department of Computer Science gain international recognition in scientific computing research during his 34 years of service. In the early 1990s, Paul's initial collaborations in numerical relativity helped to provide event signatures for the gravitational waves produced by the merger of black holes and neutron stars. In 1996, Paul was a principal investigator for the NASA Earth and Space Science Grand Challenge on Simulating the Merger of Binary Neutron Stars. Two decades later, in September 2015, gravitational waves from the collision between two black holes were detected for the very first time. The world-wide collaborative achievement was recognized with the 2017 Nobel Prize in Physics and serves as a grand example of the type of computational research and scientific advances that Paul enjoyed pursuing with colleagues. Following Paul's retirement in 2001, he held positions with the National Science Foundation as a Program Director for Computational Mathematics and at the Louisiana State University Center for Computation and Technology as a visiting professor. From the late 1970s through the 2000s, Paul was also a research consultant at Lawrence Livermore, Lawrence Berkeley, Los Alamos, and Sandia National Laboratories. The late Gene H. Golub (Stanford) was a close family friend of the Saylors and a UIUC alumnus. In 2005, Gene endowed a UIUC Computer Science faculty chair in honor of the Saylors' kindness, support, and generosity, as well as their dedication to students and the academic life. In 2015, UIUC recognized Paul's accomplishments with a Distinguished Academic Achievement Alumni Award. Paul was known by many for his keen sense of humor and good cheer. He was also known to view numerical analysis as a metaphor and, for words of encouragement, opine that "Life itself is an iterative process. Every action you take creates an error, and you hope the errors go down over time." Paul will be greatly missed by his family, friends, colleagues, and students. Amen. Condolences to the family can be offered online at https://pesaylor.com and the website will include information on establishing a Paul Saylor Fellowship in Scientific Computing at UIUC. From Joe Grcar: When I was a graduate student at the University of Illinois in Urbana, Paul Saylor was a young professor of Computer Science who along with Ahmed Sameh got me hooked on numerical analysis. A Stanford undergraduate and Rice graduate, Paul was proud to be on the Illinois faculty. It was a great department with very strong programs in NA and, of all things, parallel computing back when both were hot and going to change the world---and they did. Maybe this is a good time to memorialize the NA faculty (Gear, Sameh, Saylor, Skeel, Watanabe) and the parallel computing faculty (Kuck, Lawrie, Sameh, Dan Slotnick who many consider to be the father of parallel) and early luminaries (Don Gillies, John Pasta founder of contract research for computing at both the Department of Energy and the National Science Foundation, and Abe Taub). The last three were connected to John von Neumann, but they are another story. Paul was especially interested in department lore and would regale with anecdotes about Dan and Abe and of course Gene Golub. Paul died of a long illness this November 7 just a few days short of his dear friend. Gene always said the best measure of Paul's talents was the quality of his students. ------------------------------------------------------- From: Paola Gervasio [log in to unmask] Date: November 10, 2020 Subject: New Book, A Primer on Mathematical Modelling A Primer on Mathematical Modelling, by Alfio Quarteroni and Paola Gervasio.

These models are then used to estimate system performance, find weaknesses in real systems, and suggest improvements. This conference brings together a wide variety of mathematical methods with defence and security applications. The programme will include keynote speakers, presentations and poster sessions, as well as refreshment breaks for informal discussions. It is aimed towards mathematicians, scientists and engineers from both industry and academia, in addition to government and military personnel who have an interest in how mathematics can be applied to defence and security problems. This will be the sixth Mathematics in Defence and Security, conference albeit the first with 'Security' explicitly mentioned in the title; the previous conferences each attracted over 100 delegates from a wide range of organisations including Dstl, QinetiQ, AWE, BAE Systems, Thales, Rolls Royce, the IMA, the MoD, academia and international parties. In response to the Covid-19 situation, this event will be held virtually via Zoom Webinar. Our intention is that the scientific programme will remain very similar to that of an in-person event. ------------------------------------------------------- From: Pamela Bye [log in to unmask] Date: November 12, 2020 Subject: Mathematics of Operational Research ONLINE, Apr 2021 3rd IMA and OR Society Conference on Mathematics of Operational Research, Tuesday April 20 - Friday April 23, 2021 Online Conference via Zoom - Daily Delegate Rate Available https://ima.org.uk/14347/14347/ Innovating Mathematics for New Industrial Challenges Building on the success of the two previous conferences held in 2017 and 2019 this conference will draw together the considerable community of researchers and practitioners who develop new mathematics of relevance to, and which underpin applications in Operational Research (OR).

The journal connects methods in business, economics, engineering, mathematics and computer science in both academia and industry. Mathematical modelling of problems arising in engineering, physics, mechanics, etc. leads in many cases, directly or after a discretization process, to solving systems of linear equations of finite dimension. Besides, other problems of Numerical Analysis, such as approximation, interpolation, nonlinear systems, computation of eigenvalues, etc., lead to the resolution of large systems. Thus, it is essential to develop efficient numerical Linear Algebra methods, in both sequential and parallel environments, to solve them. The main purpose of this Special Issue is to collect the most recent methods for solving such problems and applications from a multidisciplinary approach. The guest editors of this special issue are Luca Bergamaschi ([log in to unmask]), Fernando De Teran ([log in to unmask]), and Pedro Alonso ([log in to unmask]). Authors should follow the author guidelines. All papers must be submitted via the online system https://mc.manuscriptcentral.com/compandmathmethods Authors need to make sure that they specify the paper is a contribution for "Special Issue on Linear Algebra, Matrix Analysis and Applications" and select the article type, when prompted. All papers will be peer reviewed according to the high standards of CMM. Deadline for submissions: June 30, 2021. ------------------------------------------------------- End of Digest **************************
