We calculate the homological blocks for Seifert manifolds from the exact expression for the G = SU (N ) Witten-Reshetikhin-Turaev invariants of Seifert manifolds obtained by Lawrence, Rozansky, and Mariño. For the G = SU (2) case, it is possible to express them in terms of the false theta functions and their derivatives. For G = SU (N ), we calculate them as a series expansion and also discuss some properties of the contributions from the abelian flat connections to the Witten-Reshetikhin-Turaev invariants for general N . We also provide an expected form of the S-matrix for general cases and the structure of the Witten-Reshetikhin-Turaev invariants in terms of the homological blocks.In this paper, we consider the G = SU (N ) WRT invariant on general Seifert manifolds X(P 1 /Q 1 , . . . , P F /Q F ) where P j and Q j are coprime for each j = 1, . . . , F and P j 's are pairwise coprime. We provide a formula that calculates Z a 's from which we can calculate the homological blocks exactly for G = SU (2) and as a q-series expansion for G = SU (N ) from the exact expression given by Lawrence and Rozansky [15] and Mariño [16]. We see that examples calculated in this paper fit into the expected structures of the WRT invariant for Seifert manifolds in terms of homological blocks in section 3.2.3 The reason why only abelian flat connections are taken into account, not all flat connections, is not known yet, though the resurgent analysis provide some explanation on it.The q-series in parenthesis takes a form of q 1 120 Z [[q]]. This agrees with the result of [3] on the Poincaré homology sphere Σ(2, 3, 5). As it is an integer homology sphere, there is one homological block from the trivial flat connection, which is (2.20).
