摘要
We study instanton solutions on noncommutative Euclidean 4-space which are deformations of instanton solutions on commutative Euclidean 4-space. We show that the instanton numbers of these noncommutative instanton solutions coincide with the commutative solutions and conjecture that the instanton number in R-4 is preserved for general noncommutative deformations. We also study noncommutative deformation of instanton solutions on a T-4 with twisted boundary conditions. (C) 2008 Elsevier B.V. All rights reserved.
