A presentation of the deformed W_{1+\infty} algebra    [PDF]

Noah Arbesfeld, Olivier Schiffmann

We provide a generators and relation description of the deformed W_{1+\infty}-algebra introduced in previous joint work of E. Vasserot and the second author. This gives a presentation of the (spherical) cohomological Hall algebra of the one-loop quiver, or alternatively of the spherical degenerate double affine Hecke algebra of GL(\infty).
