| Abstract: | We study the U(1) and U(2) instanton solutions of gauge theory
on general noncommutative R4. In all cases considered we obtain explicit results for the projection operators. In some
cases we computed numerically the instanton charge and found that
it is an integer independent of the noncommutative parameters
θ1,2. |
