$K$ -theoretic Coulomb branches of quiver gauge theories and cluster varieties

Gus Schrader, Alexander Shapiro

For $I^$ a quiver without 1-cycles, we show that the Braverman--Finkelberg--Najakima quantized $K$ -theoretic Coulomb branch algebra $A_{I^} $ of the corresponding quiver gau…

Quantum $S L^{+} (N, R)$ as a locally compact quantum group

K. De Commer, G. Schrader, A. Shapiro +1

We construct the first examples of purely continuous, $q$ -deformed Lie type locally compact quantum groups in higher rank. They arise from Drinfeld-Jimbo quantization, at unimodula…

The algebraic modular functor conjecture in type $A_{n}$ quantum TeichmÃ¼ller theory

Gus Schrader, Alexander Shapiro

Fock and Goncharov introduced a quantization of higher TeichmÃ¼ller theory using cluster Poisson varieties and their noncommutative deformations, associating to a complex semisimpl…
