Summary: [For the entire collection see Zbl 0535.00017.]
Given a bundle \(X\to E\to V\) with \(\pi_ 1(V)\) not zero. Besides the monodromy of local systems \(H_*(X)\) or \(\pi_*(X)\) associated to E and which appear in the \(E^ 2\)-terms of the Serre spectral sequence (or generalized Shih spectral sequence [see the author, Homotopie des espaces de sections (1982; Zbl 0535.55001)]) the differentials \(d_ 2\) of these spectral sequences bring us \(\pi_ 1(V)\) actions on \(H_*(X)\) or \(\pi_*(x)\). We explain here these actions.
