Noncommutative Instantons on R^2_{NC} x R^2_C
Keun-Young Kim, Bum-Hoon Lee, Hyun Seok Yang
We study U(1) and U(2) noncommutative instantons on R^2_{NC} x R^2_C based on the ADHM construction. It is shown that a mild singularity in the instanton solutions for both self-du…
Topological Z_{N+1} Charges on Fuzzy Sphere
Chuan-Tsung Chan, Chiang-Mei Chen, Hyun Seok Yang
We study the topological properties of fuzzy sphere. We show that the topological charge is only defined modulo N+1, that is finite integer quotient Z_{N+1}, where N is a cut-off s…
CP^n Model on Fuzzy Sphere
Chuan-Tsung Chan, Chiang-Mei Chen, Feng-Li Lin +1
We construct the CP^n model on fuzzy sphere. The Bogomolny bound is saturated by (anti-)self-dual solitons and the general solutions of BPS equation are constructed. The dimension…
