# EquivariantMap -- the class of all equivariant morphisms between GKM varieties

## Description

Given two GKM varieties $X$ and $Y$, an equivariant morphism from $X$ to $Y$ induces a map from the torus-fixed points of $X$ to the torus-fixed points of $Y$.

A EquivariantMap C is a HashTable consisting of three keys:

• source, whose value is a GKMVariety corresponding to the domain of f
• target, whose value is a GKMVariety corresponding to the codomain of f
• ptsMap, whose value is a HashTable; its keys are X.points and the values are points of Y.points that the key maps to.
