DESCRIPTION:Title: <a href="https://researchseminars.org/talk/JENTE/4/">Fr
 om the 2-1 formula for multiple zeta values to iterated beta integrals</a>
 \nby Nobuo Sato (National Taiwan University) as part of Japan Europe Numbe
 r Theory Exchange Seminar\n\n\nAbstract\nA multiple zeta value\, or MZV in
  short\, is a generalization of the Riemann zeta value at a positive integ
 er\, defined by a certain nested infinite sum. It is well known that MZV's
  satisfy a large family of linear/algebraic relations over the rationals. 
 Among such relations is the so-called two-one formula\, which was first co
 njectured by Ohno and Zudilin as a generalization of their formula and was
  later proved by Zhao in a quite ingenious but also mysterious way. In my 
 talk\, I would like to revisit the two-one formula from the viewpoint of i
 terated beta integrals introduced by Hirose and myself. Our new viewpoint 
 provides a clear understanding of the phenomena as well as a universal way
  to prove identities of similar flavors\, such as Zagier’s 2-3-2 formula
  and its generalization.\n
