  • Ivanova, Tatiana A.; Lechtenfeld, Olaf; Popov, Alexander D.; Tormählen, Maike (Amsterdam : Elsevier Science BV, 2014)
    Recently, conformal field theories in six dimensions were discussed from the twistorial point of view. In particular, it was demonstrated that the twistor transform between chiral zero-rest-mass fields and cohomology classes ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
