Folding shuffle algebras and twisted -characters
Andrei Neguţ, Keyu Wang
Using our new notion of folding shuffle algebras, we prove a conjecture of Hernandez on the equality between certain -characters of quantum untwisted affine algebra modules and…
-theoretic Hall algebras and Coulomb branches
Shivang Jindal, Andrei Neguţ
We construct a surjective homomorphism from the (suitably interpreted) double loop-nilpotent -theoretic Hall algebra to the Coulomb branch algebra of a quiver gauge theory, usin…
Borel and shifted category O
David Hernandez, Andrei Neguţ
We prove a precise relation between simple modules in the Borel category O and the shifted category O for a symmetrizable Kac-Moody Lie algebra.
A new new coproduct on quantum loop algebras
Andrei Neguţ
Quantum loop algebras generalize for simple Lie algebras , and they include examples such as quantum affinizations of Kac-Moody Lie alge…
