The monodromy theorem for compact Kaehler manifolds and smooth quasi-projective varieties KU Leuven
© 2017, Springer-Verlag Berlin Heidelberg. Given any connected topological space X, assume that there exists an epimorphism ϕ:π1(X)→Z. The deck transformation group Z acts on the associated infinite cyclic cover Xϕ of X, hence on the homology group Hi(Xϕ, C). This action induces a linear automorphism on the torsion part of the homology group as a module over the Laurent ring C[t, t- 1] , which is a finite dimensional C-vector space. We study the ...
