AbstractGeometric engineering provides a rich class of 5D supersymmetric gauge theories with eight supercharges, arising from M-theory compactification on non-compact Calabi-Yau threefolds. The counting of BPS states in the low-energy gauge theory is determined by the degeneracies of M2-branes wrapping holomorphic two-cycles in the Calabi-Yau threefold X. These degeneracies can also be calculat...
AbstractIn this talk, we will study the geometry of Coulomb branches of 4d quantum field theories and identify hidden algebraic structures within them
