Noncommutative geometry of phase space

, 2011
A version of noncommutative geometry is proposed which is based on phase-space rather than position space. The momenta encode the information contained in the algebra of forms by a map which is the noncommutative extension of the duality between the ...

Numerical Solution of Fuzzy Differential Equations of 2nd-Order by Runge-Kutta Method

Journal of Mathematical Extension, 2013
. In this paper, solving fuzzy ordinary differential equations of the n th order by Runge-Kutta method have been done, and the convergence of the proposed method is proved. This method is illustrated by some numerical examples.

Note on Gauge Theory on Fuzzy Supersphere

, 2003
We construct a supermatrix model whose classical background gives two-dimensional noncommutative supersphere. Quantum fluctuations around it give the supersymmetric gauge theories on the fuzzy supersphere constructed by Klimcik.
