Quantum superalgebras and the free-fermionic Yang-Baxter equation
Ben Brubaker, Daniel Bump, Henrik P. A. Gustafsson
The free-fermion point refers to a parametrized Yang-Baxter equation within the six-vertex model. It has been known for a long time…

The Cohomological Sarnak-Xue Density Hypothesis for
Shai Evra, Mathilde Gerbelli-Gauthier, Henrik P. A. Gustafsson
We prove the cohomological version of the Sarnak--Xue Density Hypothesis for over a totally real field and for inner forms split at all finite places. The proof relies on…

The Schützenberger involution and colored lattice models
Henrik P. A. Gustafsson, Carl Westerlund
Colored lattice models can be used to describe many different types of special functions of interest in both algebraic combinatorics and representation theory, for example Schur po…
