摘要：A lattice formulation of a three dimensional super Yang-Mills model with a twisted N = 4 supersymmetry
is proposed. The extended supersymmetry algebra of all eight supercharges is fully and
exactly realized on the lattice with a modified “Leibniz rule". The formulation we employ here is
a three dimensional extension of the manifestly gauge covariant method which was developed in
our previous proposal of Dirac-Kähler twisted N = 2 super Yang-Mills on a two dimensional lattice.
The twisted N = 4 supersymmetry algebra is geometrically realized on a three dimensional
lattice with link supercharges and the use of “shifted" (anti-)commutators. A possible solution to
the recent critiques on the link formulation will be discussed.
