Emergence of Time from Dimensional Reduction in Noncommutative Geometry
Chong-Sun Chu, Olaf Lechtenfeld
By considering a new form of dimensional reduction for noncommutative field theory, we show that the signature of spacetime may be changed. In particular, it is demonstrated that a…
Time-Space Noncommutative Abelian Solitons
Chong-Sun Chu, Olaf Lechtenfeld
We demonstrate the construction of solitons for a time-space Moyal-deformed integrable U(n) sigma model (the Ward model) in 2+1 dimensions. These solitons cannot travel parallel to…
Konishi Anomaly and Central Extension in N=1/2 Supersymmetry
Chong-Sun Chu, Takeo Inami
We show that the 4-dimensional N=1/2 supersymmetry algebra admits central extension. The central charges are supported by domain wall and the central charges are computed. We also…
Non-Commutative Geometry from Strings
Chong-Sun Chu
To appear in Encyclopedia of Mathematical Physics, J.-P. Françoise, G. Naber and T.S. Tsou, eds., Elsevier, 2006. The article surveys the modern developments of noncommutative geom…
Locality, Causality and Noncommutative Geometry
Chong-Sun Chu, Ko Furuta, Takeo Inami
We analyse the causality condition in noncommutative field theory and show that the nonlocality of noncommutative interaction leads to a modification of the light cone to the light…
