## Algebraic Combinatorics

Berlin, Germany, November 1-2, 2018

This will be a two day workshop on Algebraic Combinatorics with lectures and discussions on combinatorial, geometric, and algebraic structures related to root systems and reflection groups. It is primarily funded by the Einstein Foundation Berlin, as part of Bernd Sturmfels' Einstein Visiting Fellowship at TU Berlin. Additional funding is provided by the TU Berlin and by the DFG Heisenberg-Program.

The workshop will take place on Freie Universität Berlin Dahlem Campus. See also the companion Einstein Workshop on Geometric and Topological Combinatorics at the same location on October 29-31.

To register or to see the list of speakers, the schedule and the list of participants, please answer one of the following questions
(this is to prevent any further phishing attacks towards speakers or participants).
• What is the dimension of the Specht module for the partition $[4,3,1]$? (Hint: Use the hook length formula) OR
• What is the number of noncrossing partitions in the Weyl group of type $B_4$? (Hint: This is the Catalan number of type $B_4$) OR
• What is the number of vertices of the four-dimensional cyclohedron? (Hint: This is a central binomial coefficient)
