Description
The (2,2) GLSM Lagrangian allows for a simple presentation of a number of deformations of the IR SCFT obtained as the endpoint of the RG flow defined by the gauge theory path integral.
Typically, this only covers a subset of the deformations. In this talk I will review some work on describing the missing, so-called “non-toric” and “non-polynomial”, deformations as operators in the chiral algebra of the Lagrangian theory, and I will explain the key challenge through a construction, found together with Ronen Plesser, of a special holomorphic operator—the chiral spectral flow operator—in terms of the GLSM fields.
