“…All of the representations coming from this so-called "Galois obstruction" appear as the trivial Sp-representation [0] Sp , giving an infinite family of cokernel obstructions. Morita [12] showed that representations [k] Sp appear in the cokernel for all odd k ≥ 3, and more recently Enomoto and Satoh [5] showed that representations [1 4m+1 ] Sp appear in the cokernel as well.…”

“…Combining Hain's result above and the fact that Coker We wrote down a maximal vector of [1 k ] in [17]. In [49], Nakamura and Tsunogai gave a table of the Sp-irreducible decompositions of h Q g,1 (k) for 1 ≤ k ≤ 15, which are calculated by a computer.…”

“…Except for these results, there are few results for the cokernels of the Johnson homomorphisms of the mapping class groups. Recently, based on a work of Hain [21], Naoya Enomoto and the author proved Theorem 1.2 (Enomoto and Satoh [17]). (= Theorem 8.7.)…”
