Dear all,
there is a new formalized technique in the AFP to show that certain numbers are irrational.

Irrational Rapidly Convergent Series
by Angeliki Koutsoukou Argyraki and Wenda Li
We formalize with Isabelle/HOL a proof of a theorem by J. Hancl asserting the
irrationality of the sum of a series consisting of rational numbers, built up
by sequences that fulfill certain properties. Even though the criterion is a
number theoretic result, the proof makes use only of analytical arguments. We
also formalize a corollary of the theorem for a specific series fulfilling the
assumptions of the theorem.
