Résumé |
We consider the long-standing problem of obtaining the 3-point
functions of Toda CFT. Our main tools are topological strings and the
AGT-W relation between gauge theories and 2D CFTs. Using the refined
topological string formalism, we obtain the 5D partition functions for
the T_N theories and provide the exact AGT-W dictionary that relates
them to the Toda structure constants. Using a procedure known as
Higgsing, we manage to obtain the formula of Fateev and Litvinov for the
Toda structure constants with one semi-degenerate primary field. |
