## String-Math Seminar: Magnificent Four with color

Seminar | February 4 | 2-3 p.m. | 402 LeConte Hall

I will present the rank $N$ magnificent four theory, which is the supersymmetric localization of $U(N)$ super-Yang-Mills theory with matter on a Calabi-Yau fourfold, and conjecture an explicit formula for the partition function $Z$: it has a free-field representation, and surprisingly it depends on Coulomb and mass parameters in a simple way. Based on joint work with N.Nekrasov.
