Noncommutative Multi-instantons on R ×s 2
Generalizing self-duality on R2×S2 to higher dimensions, we consider the Donaldson-UhlenbeckYau equations on R2n×S2 and their noncommutative deformation for the gauge group U(2). Imposing SO(3) invariance (up to gauge transformations) reduces these equations to vortex-type equations for an abelian gauge field and a complex scalar on R θ . For a special S-radius R depending on the noncommutativi...
متن کاملNoncommutative Moduli for Multi-Instantons
There exists a recursive algorithm for constructing BPST-type multi-instantons on commutative R. When deformed noncommutatively, however, it becomes difficult to write down non-singular instanton configurations with topological charge greater than one in explicit form. We circumvent this difficulty by allowing for the translational instanton moduli to become noncommutative as well. This makes p...
متن کاملNoncommutative Instantons on R
We study U(1) and U(2) noncommutative instantons on RNC ×RC based on the ADHM construction. It is shown that the instanton solutions are always regular for both self-dual and anti-self-dual gauge fields even though any projected states are not involved in the ADHM construction. Furthermore the instanton number is also an integer. [email protected] [email protected] [email protected]....
متن کاملNoncommutative Instantons on Cp
We construct explicit solutions of the Hermitian Yang-Mills equations on the noncommutative space C θ . In the commutative limit they coincide with the standard instantons on CP written in local coordinates.
متن کاملInstantons on General Noncommutative R
We study the U(1) and U(2) instanton solutions of gauge theory on general noncommutative R. 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.
