Shuffle algebras for quivers as quantum groups
Andrei Neguţ, Francesco Sala, Olivier Schiffmann
We define a quantum loop group associated to an arbitrary quiver and maximal set of deformation parameters, with generators indexed by $I \times \mathbb{…
Continuum Kac-Moody algebras
Andrea Appel, Francesco Sala, Olivier Schiffmann
We introduce a new class of infinite-dimensional Lie algebras, which we refer to as continuum Kac-Moody algebras. Their construction is closely related to that of usual Kac-Moody a…
The circle quantum group and the infinite root stack of a curve (with an appendix by Tatsuki Kuwagaki)
Francesco Sala, Olivier Schiffmann
In the present paper, we give a definition of the quantum group of the circle , and its fundamental repr…
AGT relations for abelian quiver gauge theories on ALE spaces
Mattia Pedrini, Francesco Sala, Richard J. Szabo
We construct level one dominant representations of the affine Kac-Moody algebra on the equivariant cohomology groups of moduli spaces of rank one framed…
