26th International Conference on Applications of Computer Algebra

ACA 2020 will not Occur


Hello everyone. We regret to inform you that ACA'2020 will not occur. This is unfortunate as a number of really interesting sessions have been proposed, but health considerations are paramount, and at this point in time, we don't expect it will be possible to hold this conference, in Athens or elsewhere in 2020.

This announcement should come as no surprise. We expect other CA conferences, such as ISSAC, will suffer similar fates. We have decided, rather than cancel, to postpone the meeting until the situation settles down, either later in the year or more likely by one year, having it in Athens in 2021, dates to be decided later (We will pay special attention to how ISSAC is rescheduled as these two conferences were originally designed to be in sync this year). Ilias and Dimitris Simos have put a great deal of effort already in organizing this conference, and I appreciate their efforts and those of all the session organizers.
