DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ACPMS/17/">P
 ost-Lie algebras related to multiple (q-)zeta values</a>\nby Annika Burmes
 ter (Bielefeld University) as part of Algebraic and Combinatorial Perspect
 ives in the Mathematical Sciences\n\n\nAbstract\nMultiple zeta values beca
 me of more interest over the last 25 years due to their appearance in vari
 ous fields of mathematics and also physics. First\, we will describe their
  algebraic structure in terms of Hoffman’s quasi-shuffle algebras\, whic
 h are certain deformations of the usual shuffle product. Following Racinet
  this allows to relate a post-Lie algebra to the multiple zeta values\, th
 e double shuffle Lie algebra equipped with the Ihara bracket\, which gives
  a new insight into the algebraic structure of multiple zeta values. We ar
 e interested in an analog approach for multiple q-zeta values\, which are 
 certain q-series degenerating to multiple zeta values for the limit q to 1
 . In particular\, we will explain some results towards a post-Lie algebra 
 related to multiple q-zeta values.\n
