Announcement
We are pleased to announce a semester in a range of topics in algebraic geometry. The program is a part of series of research oriented
Simons Semesters at the
Banach Center in Warsaw (Poland). The Targeted Grant to Institutes of Simons Foundation is administered at
IMPAN (Institute of Mathematics of the Polish Academy of Sciences). Supplementary funding is provided by IMPAN and the
Polish Ministry of Science and Higher Education (MNiSW).
One of the previous semesters also concerned algebraic geometry: miniPAGES (April 18June 18, 2016). The list of other semesters is available here.
Focus points

Group actions: Mori Dream Spaces, $T$varieties, also toric varieties, homogeneous spaces, contact Fano manifolds, Cremona groups, actions of finite groups, $\mathbb{G}_a$ and $\mathbb{G}_m$ actions on affine varieties,

Arithmetic: arithmetic aspects of differential equations, $p$adic cohomologies, crystals, CalabiYau varieties, arithmetic aspects of mirror symmetry,
 Parametrizing varieties: Hilbert scheme of points, rational curves on manifolds, secant varieties, tensor ranks, Waring ranks and related notions with their applications to complexity theory, engineering and quantum physics.
Activities
In addition to the events listed below, weekly activities will be held at the Banach Center in Warsaw and at the University of Warsaw. These will include research seminars, lectures, and lecture series given by the leaders of our program. Participation of postdocs and PhD students will be especially encouraged.

How to Acknowledge the Semester
In publications an acknowledgement "This work was partially supported by the grant 346300 for IMPAN from the Simons Foundation and the matching 20152019 Polish MNiSW fund” would be appreciated.
Participants are also kindly asked to add a "Report number" to all publications posted on arxiv.org, which are related to participation in the Simons Semester Varieties: Arithmetic and Transformations in Warsaw Sep 1Dec 1, 2018. The code to add is:
BCSim2018s09
One can add this code:
1) upon a submission of the paper,
2) upon submitting a revision,
3) without changing the paper.
For 1), and 2), one just adds the report number as a part of Metadata.
For 3), in personal arxiv account, click "journalref" and add the code in the field "Report number".
