题目：Extended Shuffle product for multiple zeta values

摘要：In this talk, we extends the shuffle algebra to an extended shuffle algebra encoding convergent multiple zeta series with arbitrary integer arguments (not just positive ones). By replacing the weight zero Rota-Baxter (integral) operator with a differential operator, we generalize the shuffle product. We show the subspace of convergent integer-argument MZVs forms a subalgebra under this extended product. Lifting to the locality algebra of Chen symbols, we prove that summing fractions from Chen symbols defines an algebra homomorphism from this subalgebra to real numbers spanned by convergent multiple zeta series. This work is joint with Professor Li Guo,Professor Wenchuan Hu, and Professor Bin Zhang.
