[Facets-of-complexity] Today Monday Colloquium - May 10th 2021

[Günter Rote <rote@inf.fu-berlin.de>]

Today's colloquium talk was interrupted by technical problems.
We are planning to postpone it to next Monday (May 17th)

*_Time_: **Monday, **May 10th**- 16:00 h s.t.* (canceled)
*_Colloquium_: Aniket Shah (Ohio State University)*
*_Title_: A q-analogue of Brion's identity*
*_Abstract_:*

Rogers-Szegő polynomials are a family of orthogonal polynomials on the 
circle. We introduce a generalization of these polynomials which depend 
on the data of a polytope and prove a vertex sum formula for them when 
the polytope is smooth. This formula recovers Brion's formula when the 
parameter q is set to 0.
