8th polymake conference and developer meeting
February 3rd, 2017
polymake conference
On Friday there will be one or two invited talks and several tutorial and helpdesk sessions for polymake users.
There will be no conference fee.
Participants are encouraged to bring their own laptop and use them in the tutorials, preferably with an installed version of polymake. See the Perpetual Beta Section for the most recent beta version of polymake or check the Download Section for the current release. If you have any polymake problem you want to get help during the workshop please describe your problem during the sign up process.
The conference takes place in the math building of TU Berlin:
Rooms MA313/314 and MA315,
Str. des 17. Juni 136,
10623 Berlin

Richard Sieg: What's new in Normaliz?
Normaliz is an open-source software for computations in rational cones and affine monoids. Normaliz offers a rich variety of input types for cones and lattices. It can be accessed from several computer algebra systems, and provides a C++ class library for use in other software, in particular polymake.
We will introduce the two main computational goals, namely the Hilbert basis and series, and give an overview of the algorithmic ideas behind the computations. We will then present some new features in Normaliz: the subdivision of large simplicial cones for significant faster computations and the Python interface PyNormaliz, which can be used as an interface to other software packages and as an interactive shell for computations.
Lars Kastner, Kristin Shaw, Anna-Lena Winz: Cellular sheaf cohomology in Polymake
This talk will be an introduction to the topics of cellular sheaves, cosheaves and their (co)homologies, together with a live presentation of their new implementation within Polymake. In particular, we will explain how cellular sheaves on discrete objects such as polytopes, fans and tropical varieties can be used to recover geometric invariants of complex algebraic varieties. These phenomenon will be illustrated with polymake examples.
Developer Meeting
The developer meeting takes place on February 2nd and 4th.
On Thursday we will have general discussions on important topics and tickets, and assign tickets/tasks to small teams for the coding session on Saturday.
On Thursday we will go for lunch around 12:30. Everybody who is already there is welcome to join.
Official start is at 15:00 in MA 621.
On Saturday we will meet at 10:00.
