Abstract

We discuss the representation theory of non-linear chiral algebra of Gaberdiel and Gopakumar and its connection to Yangian of whose presentation was given by Tsymbaliuk. The characters of completely degenerate representations of are for generic values of parameters given by the topological vertex. The Yangian picture provides an infinite number of commuting charges which can be explicitly diagonalized in highest weight representations. Many properties that are difficult to study in picture turn out to have a simple combinatorial interpretation.
