...using Ingham Theorem ([13, Theorem4.3]) for T>2π G and G := inf k,j∈N k6= j |λk−λj| = 3π2 >0. Then γ1 is surjective and the proof is achieved thanks to the Generalized Inverse Function Theorem ([14], p. 240), which ensures that the map α1 is locally surjective. Remark. We point out that one can achieve the result of Theorem 4 for any positive time T >0 by using Haraux Theorem ([13, Theorem4.5...

...unction is equivalent to prove the local right invertibility of the map α1 for a T >0 (in other words the local surjectivity). To this end, we want to use the Generalized Inverse Function Theorem ([14], p. 240) and we study the surjectivity of the Fr¨ı¿chet derivative of α1, γ1(v) := (duα1(0)) · v, the sequence with elements γk,1(v) : = ˝ φk(T),−i ZT 0 e−iA(T−s)v(s)Be−iAsφ 1ds ˛ = −i ZT 0 v(s)ei(λ...
