| ABSTRACT: |
We propose N=4 twisted superspace formalism in four dimensions by
introducing Dirac-Kahler twist. We can then construct twisted N=2 super
Yang-Mills action using a superconnection formalism of twisted superspace.
In addition we construct a off-shell Donaldson-Witten theory coupling to a
twisted hypermultiplet. We show that this action possesses N=4 twisted
supersymmetry at on-shell level.
