A single point as a Calabi-Yau zerofold

We give a brief account of a non-abelian GLSM that describes a Calabi-Yau zerofold, in this case a single point, in the “large volume” phase. The other phase is non-regular, i.e. there is no clear separation between the gauge and the matter sectors. Prepared for the proceedings of the MATRIX program “The geometry of moduli spaces in string theory” held in September 2024.
