We find them using S-duality symmetry of the type IIB formulation. The result is encoded in a set of holomorphic functions on the twistor space of $M_H$ and includes all orders of the instanton expansion. %G English %2 https://hal.science/hal-00958486/document %2 https://hal.science/hal-00958486/file/PhysRevD.90.11203.pdf %L hal-00958486 %U https://hal.science/hal-00958486 %~ CNRS %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
