Topological hypermultiplet on N=2 twisted superspace in four dimensions
Junji Kato, Akiko Miyake
We propose a N=2 twisted superspace formalism with a central charge in four dimensions by introducing a Dirac-Kähler twist. Using this formalism, we construct a twisted hypermultip…
Uniqueness of the modified Schroedinger map in H^{3/4+e}(R^2)
Jun Kato, Herbert Koch
We establish local well-posedness of the modified Schroedinger map in H^s, s>3/4.
N=4 Twisted Superspace from Dirac-Kahler Twist and Off-shell SUSY Invariant Actions in Four Dimensions
Junji Kato, Noboru Kawamoto, Akiko Miyake
We propose N=4 twisted superspace formalism in four dimensions by introducing Dirac-Kahler twist. In addition to the BRST charge as a scalar counter part of twisted supercharge we…
Twisted Superspace for N=D=2 Super BF and Yang-Mills with Dirac-Kähler Fermion Mechanism
Junji Kato, Noboru Kawamoto, Yukiya Uchida
We propose a twisted D=N=2 superspace formalism. The relation between the twisted super charges including the BRST charge, vector and pseudo scalar super charges and the N=2 spinor…
