Section report on the GAMM Annual Meeting 2018

The 89th Annual Meeting of the GAMM took place at the Technische Universität München on 19-23 March 2018. This was a highly enjoyable conference in a picturesque (and snowy!) city, at the impressive venue of the TU.

A highlight of the conference was the session “Applied and Numerical Linear Algebra“, expertly organised by Iveta Hnetynkova and Robert Luce. This stream featured 36 interesting and wide-ranging talks, many of them by members of the GAMM Activity Group, spanning three days of the meeting. For example, Petr Tichý described bounds of the residual norm for ideal GMRES using the field of values of the given matrix and its inverse, Iveta Hnetynkova discussed iterative methods for inverse problems containing additive noise, and Daniel Kressner surveyed results on Krylov subspace methods for updating matrix functions. Zdeněk Strakǒs gave a fascinating insight into operator preconditioning and decomposition of Hilbert spaces, and Tessa Uroić outlined a selective algebraic multigrid algorithm for coupled pressure-velocity systems arising from the Finite Volume Method. It was a pleasure hearing about state-of-the-art research in these fields, as well as many others.

Linear algebra also featured prominently in other parts of the conference, such as within the minisymposium “PDE Constrained Optimization under Uncertainty”, as well as a number of the plenary lectures, which showcased the importance of our subject area for a range of applications. Overall this was a highly informative and well-organised meeting, with research in linear algebra playing a key role in the success of the conference.
