SUMMARY:Bernoullis Tafelrunde: Riccardo Tosi (Essen)
DESCRIPTION:The values of the Riemann zeta function at odd positive integer
 s greater than 1 are conjectured to be transcendental\, yet even their irr
 ationality remains a mostly open question. Recently\, new inputs to irrati
 onality proofs have come from geometric methods\, especially in connection
  with periods of hyperplane arrangements. In this talk\, we will have a lo
 ok at some classical strategies to prove the irrationality of a number. Th
 en\, we will realize zeta values as periods of some algebraic varieties an
 d finally we will try to understand how this geometric perspective can giv
 e further impulse to irrationality proofs for zeta values.\\r\\nabstract [
