The sum formulas for multiple zeta(-star) values and symmetric bear a striking resemblance. We explain the resemblance in rather straightforward manner using an identity that involves Schur zeta values. also obtain formula polynomial terms of generating functions, simultaneously generalizing

In this paper we present some new identities for multiple polylogarithms (abbr. MPLs) and harmonic star sums MHSSs) by using the methods of iterated integral computations logarithm functions. Then, applying these formulas obtained, establish explicit relations between Kaneko-Yamamoto type zeta values K-Y MZVs), MZVs) MPLs. Further, find MZVs MZSVs). Furthermore, define an Apéry-type variant MZS...
