On the Consistency of Twisted Gauge Theory
S. Giller, C. Gonera, P. Kosinski +1
It is argued that the twisted gauge theory is consistent provided it exhibits also the standard noncommutative gauge symmetry.
Global Symmetries of Noncommutative Space-time
C. Gonera, P. Kosinski, P. Maslanka +1
The global counterpart of infinitesimal symmetries of noncommutative space-time is discussed.
Space-time symmetry of noncommutative field theory
C. Gonera, P. Kosinski, P. Maslanka +1
We consider the deformed Poincare group describing the space-time symmetry of noncommutative field theory. It is shown how the deformed symmetry is related to the explicit symmetry…
On the relations between osp(2,2) and the quasi exactly solvable systems
Yves Brihaye, Stefan Giller, Piotr Kosinski
By taking a product of two sl(2) representations, we obtain the differential operators preserving some space of polynomials in two variables. This allows us to construct the repres…
Galilean invariance in 2+1 dimensions
Y. Brihaye, C. Gonera, S. Giller +1
The Galilean invariance in three dimensional space-time is considered. It appears that the Galilei group in 2+1 dimensions posses a three-parameter family of projective representat…
Projectivised representations of
Y. Brihaye, S. Giller, P. Kosinski
We construct representations of the enveloping algebra in terms of finite difference operators and we discuss this result in the framework of quasi-exactly-solvable…
