Infinite multiplicity of roots of unity of the Galois group in the representation on elliptic curves

Let K be a number field, an algebraic closure of K and E/K an elliptic curve defined over K. Let G_K be the absolute Galois group of over K. This paper proves that there is a subset Σ⊆G_K of Haar measure 1 such that for every σ∈Σ, the spectrum of σ in the natural representation of G_K consists of all roots of unity, each of infinite multiplicity. Also, this paper proves that any complex conjugation automorphism in G_K has the eigenvalue -1 with infinite multiplicity in the representation space of G_K.
