Abstract: In 2019, the speaker and Shuji Yamamoto (Keio University) gave a new proof of the duality for multiple zeta values by series manipulation. The key ingredients were the connected sum and its transport relations. 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 polylogarithms which contains Ohno's relations. This is joint work with Hanamichi Kawamura (Seifu Senior High School) and Takumi Maesaka (Kanazawa University Senior High School).
