  • Sasakian quiver gauge theories and instantons on the conifold 
    Geipel, Jakob C.; Lechtenfeld, Olaf; Popov, Alexander D.; Szabo, Richard J. (Amsterdam : Elsevier Science Bv, 2016)
    We consider Spin(4)-equivariant dimensional reduction of Yang Mills theory on manifolds of the form M-d x T-1,T-1, where M-d is a smooth manifold and T-1,T-1 is a five-dimensional Sasaki Einstein manifold Spin(4)/U(1). We ...
  • Sigma-model limit of Yang–Mills instantons in higher dimensions 
    Deser, Andreas; Lechtenfeld, Olaf; Popov, Alexander D. (Amsterdam : Elsevier Science BV, 2015)
    We consider the Hermitian Yang–Mills (instanton) equations for connections on vector bundles over a 2n-dimensional Kähler manifold Xwhich is a product Y×Zof p-and q-dimensional Riemannian manifold Yand Zwith p+q=2n. We ...
  • Yang-Mills instantons and dyons on homogeneous G(2)-manifolds 
    Bauer, Irina; Ivanova, Tatiana A.; Lechtenfeld, Olaf; Lubbe, Felix (New York, NY : Springer International Publishing, 2010)
    We consider LieG-valued Yang-Mills fields on the space RxG/H, where G/H is a compact nearly Kahler six-dimensional homogeneous space, and the manifold RxG/H carries a G(2)-structure. After imposing a general G-invariance ...
  • Yang-Mills instantons on cones and sine-cones over nearly Kahler manifolds 
    Gemmer, Karl-Philip; Lechtenfeld, Olaf; Noelle, Christoph; Popov, Alexander D. (New York, NY : Springer International Publishing, 2011)
    We present a unified eight-dimensional approach to instanton equations on several seven-dimensional manifolds associated to a six-dimensional homogeneous nearly Kahler manifold. The cone over the sine-cone on a nearly ...
