Abstract: This is the third paper of a series which describes a conjectural analog of the affine Grassmannian for affine Kac–Moody groups (also known as the double affine Grassmannian). The current paper is dedicated to describing a conjectural analog of the convolution diagram for the double affine Grassmannian and affine zastava.

Key words and phrases: affine Grassmannian, chainsaw quiver, dented chainsaw quiver, rift quiver.
