DESCRIPTION:Title: <a href="https://researchseminars.org/talk/JENTE/12/">C
 ombinatorial multiple Eisenstein series</a>\nby Annika Burmester (Universi
 tät Hamburg) as part of Japan Europe Number Theory Exchange Seminar\n\n\n
 Abstract\nMultiple q-zeta values are formal q-series\, which return multip
 le zeta values as q goes to 1. The space of multiple q-zeta values can be 
 spanned by various different models. In this talk\, we will report on our 
 search for a model that is graded with respect to the usual multiplication
  of q-series. More precisely\, we are interested in q-series whose generat
 ing series yield a swap invariant and symmetril bimould. In lowest depth\,
  these q-series are given by Eisenstein series and their derivatives. Ther
 efore we call this model the combinatorial multiple Eisenstein series. The
  construction relies on the bi-brackets introduced by Bachmann\, as well a
 s a rational solution to the classical double shuffle equations of multipl
 e zeta values. This talk is based on joint work with H. Bachmann.\n
