for Analysis
its Applications
and Computation

Dear ISAAC members,

some time has passed since my last letter on March 23rd, 2020. The Corona virus has spread  all over the world. I found out from ISAAC members that they were infected with the virus. Of course the entire ISAAC community hopes that all affected colleagues are healthy again. Our life has changed fundamentally in the past few weeks. Public life has been severely restricted in most countries.

Universities are closed.  But in most cases, as mathematicians, we have the advantage that we can continue to work from home. This enabled us to complete our contributions for the Proceedings of the 12th ISAAC congress. Teaching as a digital transfer of knowledge was certainly a new challenge.

In many countries, strict restrictions will be relaxed in the near future. Connected with this is the hope of being able to hold or take part in workshops or congresses again. On the horizon, I can see already a small light that brings us to the 13th ISAAC  congress next year in Ghent in Belgium. I ask our ISAAC members to plan already, to organize sessions during the congress and to invite colleagues from their research area to contribute to the sessions. Usually, the members of the special interest groups are very active in this matter.

I wish you a good and successful time, many new mathematical results and a get together next year

in Ghent,

stay healthy

The International Society for Analysis, its Applications and Computation (ISAAC) is a non-profit organization established in 1994 to promote and advance analysis, its applications, and its interaction with computation. Analysis is understood here in the best sense of the word, including differential equations, integral equations, functional analysis, and function theory.

New Tools for Nonlinear PDEs and ApplicationMathematical Analysis and Applications - Plenary LecturesIt is imagined that within ISAAC certain special interests groups will exist which organize workshop

s and mini-symposia at the ISAAC meetings. These special interests groups are to operate independently and to have representation on the ISAAC Board.

With this objective, international meetings shall be organized by ISAAC for the presentation and discussion of research on analysis in the above context. ISAAC will also support, from time to time, other activities, such as summer schools and exchange of scientists.
