Description
A singular subvariety in a smooth ambient space has a characteristic class in the cohomology of the ambient space. When the ambient space is the moduli space of interesting algebraic objects, then information on the characteristic classes can be turned to enumerative geometry results. This approach to enumeration is traditionally used when the ambient space is a Grassmannian or some related homogeneous space. In this talk we will introduce characteristic classes of singularities in more general ambient spaces: Cherkis bow varieties. In particular we will study the so-called elliptic stable envelope classes, and show their (conjectural) 3d mirror symmetry property.
