Abstract
We study the structure of modules of corner vertex operator algebras arrising at junctions of interfaces in N=4 SYM. In most of the paper, we concentrate on truncations of W1+ associated to the simplest trivalent junction. First, we generalize the Miura transformation for WN1 to a general truncation YN1,N2,N3. Secondly, we propose a simple parametrization of their generic modules, generalizing the Yangian generating function of highest weight charges. Parameters of the generating function can be identified with exponents of vertex operators in the free field realization and parameters associated to Gukov-Witten defects in the gauge theory picture. Finally, we discuss some aspect of degenerate modules. In the last section, we sketch how to glue generic modules to produce modules of more complicated algebras. Many properties of vertex operator algebras and their modules have a simple gauge theoretical interpretation.
