Super Liouville conformal blocks from N = 2 SU(2) quiver gauge theories

The conjecture about the correspondence between instanton partition functions in the N = 2 SUSY Yang-Mills theory and conformal blocks of two-dimensional conformal field theories is extended to the case of the N = 1 supersymmetric conformal blocks. We find that the necessary modification of the moduli space of instantons requires additional restriction of Z(2)-symmetry. This leads to an explicit form of the N = 1 superconformal blocks in terms of Young diagrams with two sorts of cells.
