“…Recently, Bundschuh and Väänänen [BV13] proved that µ(S(1/b)) ≤ 2.929 and µ(T (1/b)) ≤ 3.555 for all integers b ≥ 2. Our next result gives the exact irrationality exponent of the Stern number and also that of the twisted Stern number, and it will be proved in Section 7.…”

“…We now apply Theorem 6 with F (z) = S(z) and G(z) = S(z 4 ). The use of (7) gives d = 4, r = 1 and F (z 4 ) = G(z), G(z 4 ) = −zF (z) + (1 + z + z 2 )G(z).…”

“…Note also that in [4] we proved the algebraic independence of Γ σ (z) and its twist. The sole transcendence over C(z) of each of the functions Γ σ , Γ α , Γ β will now be generalized in a different direction.…”
