Matrix Schubert varieties and Gaussian conditional independence models
Alex Fink, Jenna Rajchgot, Seth Sullivant
Matrix Schubert varieties are certain varieties in the affine space of square matrices which are determined by specifying rank conditions on submatrices. We study these varieties f…
Lower bound cluster algebras: presentations, Cohen-Macaulayness, and normality
Greg Muller, Jenna Rajchgot, Bradley Zykoski
We give an explicit presentation for each lower bound cluster algebra. Using this presentation, we show that each lower bound algebra Grobner degenerates to the Stanley-Reisner sch…
Three combinatorial formulas for type A quiver polynomials and K-polynomials
Ryan Kinser, Allen Knutson, Jenna Rajchgot
We provide combinatorial formulas for the multidegree and K-polynomial of an arbitrarily oriented type A quiver locus. These formulas are generalizations of three of Knutson-Miller…
