Elliptic stable envelopes of affine type $A$ quiver varieties

We generalize Smirnov’s formula for the elliptic stable envelopes of the Hilbert scheme of points in ${\mathbb{C}}^2$ to the case of affine type $A$ Nakajima quiver varieties constructed with positive stability condition. We allow for arbitrary choices of polarization and a fairly general choice of chamber. This paper is a companion to the Maple code developed by the author, which implements the formulas described in this paper and is available on the author’s website.
