Noncommutative Solitons and the W_{1+\infty} Algebras in Quantum Hall Theory
Chuan-Tsung Chan, Jen-Chi Lee
We show that U(\infty) symmetry transformations of the noncommutative field theory in the Moyal space are generated by a combination of two W_{1+\infty} algebras in the Landau prob…

Equivalent Relations between Quantum Dynamics as Derived from a Gauge Transformation
Chuan-Tsung Chan, Chun-Khiang Chua
Equivalent relations between quantum mechanical systems in the Robertson-Walker (RW) background metric and quantum dynamics with an induced quadratic background potential are deriv…
