Abstract:
A new proof of the fact that π2 is transcendental is proposed. A modification of Hermite's method for an expressly constructed Nikishin system is used. The Beukers integral, which was previously used to prove Apéry's theorem on the irrationality of ζ(2) and ζ(3) is a special case of this construction.
