We discuss an explicit field theory construction of three dimensional mirrors
for a large sub-class of quiver gauge theories involving unitary and special
unitary gauge nodes with matter in fundamental and bifundamental
representations. For this sub-class of theories, one can deploy a sequence of
IR dualities and certain Abelian field theory operations to reduce the
aforementioned problem to a problem of finding the 3d mirror of a simpler
unitary quiver gauge theory. We illustrate the construction with a linear
quiver consisting of unitary and special unitary gauge nodes.Comment: 6 pages, 6 figures, figures are color-code
