cotangent n.【數學】余切。

cotar

Furthermore , in the noncommutative chern - simons theory for the quantum hall effect , the constrain equation with quasiparticle source is also identified with the moment map eqaution of the noncommutative sun ( t ) cotangent bundle with marked points 而且,在量子hall效應的非對易陳- simons理論里,具有準粒子源的約束方程也與具有marked點的非對易su _ n ( t )余切叢的momentmap方程相同。

The moment map of this twisted cotangent sun ( t ) bundle is matched to the d - equation with fayet - illiopoulos source term , so the dynamics of the noncommutative solitons becomes that of the brane 我們由此扭曲的su _ n ( t )余切叢的momentmap給出了有fayt - illiopoulos源的d -方程,由此非對易孤立子的動力學就變成brane的動力學。
