Some Remarks on Noncommutative Instantons (1503.01553v1)
Published 5 Mar 2015 in math.DG, math-ph, and math.MP
Abstract: We make some comments on noncommutative $U(N)$-instantons on $\mathbb{R}4_{\theta}$. We elaborate on the equations for the ASD-connection for free modules. Further we make some remarks on the computation of the topological index of ADHM instantons.
