Minnesota Research Workshop in Algebra & Combinatorics

MRWAC is a research workshop designed to foster collaboration within the combinatorics and algebra group at the University of Minnesota. It focuses on current graduate students and postdocs and Ph.D. alumni. Information about current and previous workshops can be found below, where an asterisk* indicates the organizer(s).


MRWAC 2023 will take place from May 15th to 19th. Click here for this year's website.


The second edition of MRWAC took place from May 23rd to May 27th, the week after OPAC.


Robbie Angarone*, Esther Banaian, Hannah Burson, Elise Catania, Angel Chavez, Sunita Chepuri, Galen Dorpalen-Barry, Tara Gomes, Emily Gunawan, Daoji Huang, Trevor Karn*, Elizabeth Kelley, Anastasia Nathanson, Sasha Pevzner, Toby Ramaswamy, Mahrud Sayrafi, Carolyn Stephen, Eduardo Torres Davila, Sylvester Zhang*.

  1. Sylvester Zhang. Positivity of %-immanants. (Problem by Pasha Pylyavskyy)
  2. Emily Gunawan. Volumes of pattern-avoiding polytopes and Cambrian lattices.
  3. Sasha Pevzner. $P$-partition Rings and Linear Extensions of Posets.
  4. Sunita Chepuri. Trip permutations for unreduced plabic graphs.
  5. Mahrud Sayrafi. Toric varieties and problems of algebraic combinatorics.
  6. Esther Banaian. Skew-symmetrizable Markov Numbers.


The first edition (called "Combinatorics Working Groups") was held virtually in 2020 in order to fill the gap left by the GRWC which was canceled due to COVID-19.
