Modified Einstein equations from the 1-loop effective action of the IKKT model
Kaushlendra Kumar, Harold C. Steinacker
We derive the equations of motion that arise from the one-loop effective action for the geometry of 3+1 dimensional quantum branes in the IKKT matrix model. These equations are cas…

On Yang-Mills fields from anti-de Sitter spaces
Kaushlendra Kumar
Motivated by some recent progress involving a non-compact gauge group, we obtain classical gauge fields using non-compact foliations of anti-de Sitter space in 4 dimensions (requir…

Exact gauge fields from anti-de Sitter space
Savan Hirpara, Kaushlendra Kumar, Olaf Lechtenfeld +1
In 1977 Lüscher found a class of SO(4)-symmetric SU(2) Yang-Mills solutions in Minkowski space, which have been rederived 40 years later by employing the isometry $S^3\cong\mathrm{…
