FORMAT
The format of the conference switched to a virtual form due to the conditions related to the pandemic and the impossibility to maintain part of the funding for a further date.
We also decided to shrink the global time in front of the screen, because in this exceptional period almost everybody has personal or teaching duties.
Moreover, we needed to take into account the fact that the speakers came from different time zones.
For these reasons the schedule of live-talks was reduced to the short interval of time which is (relatively) compatible with European and US working time.
The other talks were pre-recorded and could be watched by the audience in the complement of the schedule time.
In order to increase the connections between the participants, the new format included a system of chats
where the participants could communicate and ask questions about the talks.
For every talk, a link to a dedicated virtual room
was activated, permitting to the audience to communicate with the speakers using ZULIP (an open source chat and collaborative software).
We maintained ZULIP ongoingly active for the total time of the conference (day and night) in order to permit exchanges between people of different time zones.
IMPORTANT : Latex math symbols are supported by Zulip here is an example
All talk have been recorded and uploaded as soon as possible (ideally few time after the talk) in the
dedicated page.
ACKNOWLEDGMENTS
The organizers wish to thank all participants for their patience.
We are also grateful to all of the speakers for their work with the videos and their help in the organization,
which made this meeting possible in such a short time and difficult circumstances.
We are grateful to all the sponsors which made this meeting possible.
Finally, we wish to express our gratitude to Fanny Bastien for her work on the poster and the videos.

DESCRIPTION
The theory of Berkovich spaces is a powerful and elegant approach to analytic geometry over
non-archimedean fields. Over the past decade it has found many striking applications in areas such
as arithmetic geometry, p-adic differential equations, and dynamics. Running through many of these
recent developments is a thread of tropical geometry. In some cases the tropical link is already firmly
established, while in others it is not yet more than a promising hint. Our view is that there is now an
exciting potential to forefront the role of Tropical geometry while exploring the application
of Berkovich theory in the intersecting areas of arithmetic D-modules, non-archimedean
representation theories and p-adic local systems. This conference brings together leading experts
in each of these areas in order to energize this vision and establish appropriate links.
With this workshop we would like to promote the interaction between the following five fields:
Berkovich spaces
Tropical geometry
p-adic differential equations
Arithmetic D-modules and representations of p-adic Lie groups
Arithmetic applications of p-adic local systems
While the first two are already tightly linked, the role of Berkovich spaces in the last ones is only emerging
and within this, the role of tropical geometry has not yet been explored. More generally, we consider this
conference to be a good opportunity to study new techniques recently introduced into the field. We are
convinced that each of these areas has plenty of potential and that a fruitful interaction between them
might nourish their development.
The aim of the conference is precisely to give leading experts in these each of these domains the
opportunity to meet, present their last results and open challenges, and encourage an exchange that
will drive forward these exciting and rapidly developing subjects.
