DESCRIPTION:Title: <a href="https://researchseminars.org/talk/JENTE/11/">M
 ultivariable connected sums and transport relations</a>\nby Shin-ichiro Se
 ki (Tohoku University) as part of Japan Europe Number Theory Exchange Semi
 nar\n\n\nAbstract\nIn 2019\, the speaker and Shuji Yamamoto (Keio Universi
 ty) gave a new proof of the duality for multiple zeta values by series man
 ipulation. The key ingredients were the connected sum and its transport re
 lations. In this talk\, we introduce the multivariable connected sum which
  generalizes Seki-Yamamoto's one\, and show new transport relations. As an
  application\, we obtain a class of functional relations among multiple po
 lylogarithms which contains Ohno's relations. This is joint work with Hana
 michi Kawamura (Seifu Senior High School) and Takumi Maesaka (Kanazawa Uni
 versity Senior High School).\n
