Simple Calculation of Instanton Corrections in Massive N=2 SU(3) SYM
Holger Ewen, Kristin Foerger
We give an explicit derivation of the Picard-Fuchs equations for N=2 supersymmetric SU(3) Yang-Mills theory with massive hypermultiplets in the fundamental representation.…
Prepotentials in N=2 Supersymmetric SU(3) YM-Theory with Massless Hypermultiplets
Holger Ewen, Kristin Foerger, Stefan Theisen
We explicitly determine the instanton corrections to the prepotential for N=2 supersymmetric SU(3) Yang-Mills theory with massless hypermultiplets in the weak coupling regions $u\t…
Classification of the GL(3) Quantum Matrix Groups
Holger Ewen, Oleg Ogievetsky
We define quantum matrix groups GL(3) by their coaction on appropriate quantum planes and the requirement that the Poincare series coincides with the classical one. It is shown tha…
Jordanian Solutions of Simplex Equations
Holger Ewen, Oleg Ogievetsky
We construct for all a solution of the Frenkel--Moore --simplex equation which generalizes the --matrix for the Jordanian quantum group.
