This version introduces: - Krylov subspace projection-based solvers for Lyapunov and Riccati equations - the first supported unsymmetric equation (the sparse-dense Sylvester equation) - a new logging tool that allows to write output not only to the console but also to structured logfiles (Markdown and LaTeX and HTML files including figures, similar to what publish produces in MATLAB) Moreover, existing solver have received additional features and bug-fixes.

This book is focused on the numerical discretization of ordinary differential equations (ODEs), under several perspectives. The attention is first conveyed to providing accurate numerical solutions, then it moves to a more modern vision of numerical approximation, oriented to reproducing qualitative properties of the continuous problem along the discretized dynamics over long times. The book finally performs some steps in the direction of stochastic differential equations (SDEs), with the intention of offering useful tools to generalize the techniques introduced for the numerical approximation of ODEs to the stochastic case, as well as of presenting numerical issues natively introduced for SDEs. The book is the result of an intense teaching experience as well as of the research carried out in the last decade by the author. It is both intended for students and instructors: for the students, this book is comprehensive and rather self-contained; for the instructors, there is material for one or more monographic courses on numerical ODEs/SDEs and related topics. In this respect, the book can be followed in its designed path and includes motivational aspects, historical background, examples and software implemented in Matlab, that can also be useful for the laboratory part of a course on numerical ODEs/SDEs. The style of the book joins rigor with readability.

The series will restart on October 2, 2023. Seminars will take place on Tuesday at 4:00 pm CEST, 10:00 am EDT, 07:00 am PDT, on a weekly basis via zoom. Please note that the opening seminar is on October 2, which is a Monday. Starting with the second seminar, we will return to our usual schedule, i.e., Tuesday. The main purpose of the NA G-ROMs seminar series is to serve as a forum for the Galerkin and Petrov-Galerkin reduced order model community to exchange their views on both the achievements and the "nagging" open problems in the numerical analysis of G-ROMs, e.g., proper orthogonal decomposition (POD), reduced basis method (RBM), and related techniques. The NA G-ROMs seminar series aims at fostering the exchange of ideas among the G-ROM community members who are genuinely interested in the development of the mathematical foundations of G-ROMs and, in particular, bringing the G-ROM numerical analysis to a level comparable to that of classical numerical methods, e.g., the finite element method.

Martin [log in to unmask] Date: September 22, 2023 Subject: Introduction to Gridap, Australia, Nov 2023 Introduction to Gridap: Simulating PDEs using finite elements in Julia Location: Australian National University, Canberra, Australia Dates: November, 28 - 29 Nov, 2023 This two-day hands-on workshop will showcase the main features of Gridap, an ecosystem of Julia packages for the simulation of problems governed by PDEs. Gridap has a very expressive user interface, allowing one to solve complex PDE systems by stating the problem using whiteboard notation. It implements multiple state-of-the-art finite element methods that can efficiently exploit large-scale HPC supercomputers. The workshop will be tutorial-based and will cover the main features of Gridap, its application to several problems, and its deployment in distributed memory machines. There will also be a brief introduction to finite element methods addressed to participants without previous background in these techniques. The emphasis will be mainly on presenting the main software abstractions underlying these packages and how these can be combined to solve a variety of PDEs with application to different problems in science and engineering. The choice of the PDE systems to be discussed in the workshop will be based on the participant's interests gathered during registration. Funding is available to cover the accommodation and travel expenses of research students. Participants must bring their own laptops.
