Algebraic properties of the monopole formula
Amihay Hanany, Marcus Sperling
The monopole formula provides the Hilbert series of the Coulomb branch for a 3-dimensional N=4 gauge theory. Employing the concept of a fan defined by the matter content, and summi…
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…
