Degenerate twisted traces on quantized Kleinian singularities of type A
Zev Friedman, Ben Webster
We study the space of non-degenerate traces on quantized Kleinian singularities of type A by studying their complement, the degenerate traces. In particular, we find the dimension…

Functoriality of Coulomb branches
Tom Gannon, Ben Webster
We prove that the affine closure of the cotangent bundle of the parabolic base affine space for or is a Coulomb branch, which confirms a conjecture…
