On the Milnor Monodromy of the Exceptional Reflection Arrangement of Type $G_{31}$
Documenta mathematica, Tome 23 (2018), pp. 1-14
Combining recent results by A. D. Mačinic et al. [Doc. Math. (Bielefeld) 22, 135–150 (2017; Zbl 1358.14020)] with a spectral sequence and computer aided computations, we determine the monodromy action on H1(F,C), where F denotes the Milnor fiber of the hyperplane arrangement associated to the exceptional irreducible complex reflection group G31. This completes the description given by the first author of such monodromy operators for all the other irreducible complex reflection groups.
