An interesting family of non-Lagrangian four-dimensional N=2, d=4 supersymmetric quantum field theories called T_N-theories is predited by string theory. The geometric engineering of these theories gives a prediction for the partition functions of these theories by topological vertex methods. Joint work in progress with I. Coman-Lohi and Elli Pomoni will clarify the relation of these partition function to conformal blocks in Toda CFT, and to the quantisation of moduli spaces of flat SL(N) connections on the three-punctured sphere.
