The Six-Vertex Yang-Baxter Groupoid
Daniel Bump, Slava Naprienko
A parametrized Yang-Baxter equation is usually defined to be a map from a group to a set of R-matrices, satisfying the Yang-Baxter commutation relation. These are a mainstay of sol…

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…
