Coulomb branch localization, quasimaps, and surface counting in Calabi--Yau fourfolds
Duiliu-Emanuel Diaconescu, Nicolo Piazzalunga
We present a string theoretic approach to surface counting in local Calabi--Yau fourfolds via supersymmetric localization in topologically twisted four-dimensional gauge theories.…

Global magniicence, or: 4G Networks
Nikita Nekrasov, Nicolo Piazzalunga
The global magnificent four theory is the homological version of a maximally supersymmetric -dimensional gauge theory on a Calabi-Yau fourfold fibered over a circle. In the…
