A presentation of the deformed W1+∞ algebra
Abstract
We provide a generators and relation description of the deformed W1+∞-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(∞).
