Multiplicative vertex algebras and quantum loop algebras
Henry Liu
We define a multiplicative version of vertex coalgebras and show that various equivariant K-theoretic constructions of Hall algebras (KHAs) also admit a compatible multiplicative v…

Equivariant K-theoretic enumerative invariants and wall-crossing formulae in abelian categories
Henry Liu
We provide a general framework for wall-crossing of equivariant K-theoretic enumerative invariants of appropriate moduli stacks , by lifting Joyce's homological unive…

A Representation-Theoretic Approach to -Characters
Henry Liu
We raise the question of whether (a slightly generalized notion of) -characters can be constructed purely representation-theoretically. In the main example of the quantum toroi…
