We propose a new generalization of the Yang-Baxter equation, where the
R-matrix depends on cluster Tex-variables in addition to the spectral
parameters. We point out that we can construct solutions to this new equation
from the recently-found corr...

We introduce a class of new integrable lattice models labeled by a pair of
positive integers N and r. The integrable model is obtained from the Gauge/YBE
correspondence, which states the equivalence of the 4d N=1 S^1 \times S^3/Z_r
index of a larg...
