The target space expression for the coefficients of the holomorphic anomaly equation for open strings are obtained. Furthermore, open/closed string duality is proved from a judicious integration over the open string fields. In particular, by restriction to the case of independence on continuous open moduli, the shift formulas of [7] are reproduced and shown therefore to encode the data of a closed string dual. %B JHEP 06(2010)063 %G en_US %U http://hdl.handle.net/1963/3855 %1 854 %2 Physics %3 Mathematical Physics %$ Submitted by Andrea Wehrenfennig (andreaw@sissa.it) on 2010-04-27T10:19:29Z\\nNo. of bitstreams: 1\\nBonelli_1003.2519v2.pdf: 244116 bytes, checksum: e9e48e420eda839f478ab8a4da3e7136 (MD5) %R 10.1007/JHEP06(2010)063
