Instantons on conical half-flat 6-manifolds
Severin Bunk, Olaf Lechtenfeld, Alexander D. Popov +1
We present a general procedure to construct 6-dimensional manifolds with SU(3)-structure from SU(2)-structure 5-manifolds. We thereby obtain half-flat cylinders and sine-cones over…
Two-loop results on the renormalization of vacuum expectation values and infrared divergences in the FDH scheme
Christoph Gnendiger, Adrian Signer, Marcus Sperling +2
Recent progress in the understanding of vacuum expectation values and of infrared divergences in different regularization schemes is reviewed. Vacuum expectation values are gauge a…
Instantons on sine-cones over Sasakian manifolds
Severin Bunk, Tatiana A. Ivanova, Olaf Lechtenfeld +2
We investigate instantons on sine-cones over Sasaki-Einstein and 3-Sasakian manifolds. It is shown that these conical Einstein manifolds are K"ahler with torsion (KT) manifolds adm…
