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).

Schedule
Problems
- Sarah Brauner. Spectra of shuffling operators.
- Pasha Pylyvaskyy. Positivity in LP algebras.
- Galen Dorpalen-Barry. Homology Concentration in $U$-Nucleus Complexes.
- Trevor Karn. Type $B$ Matroid Kazhdan-Lusztig Polynomials. (Problem by Kayla Wright.)
