Shuffle products for multiple zeta values and partial fraction decompositions of zeta-functions of root systems
Yasushi Komori, Kohji Matsumoto, Hirofumi Tsumura
The shuffle product plays an important role in the study of multiple zeta values. This is expressed in terms of multiple integrals, and also as a product in a certain non-commutati…
On Witten multiple zeta-functions associated with semisimple Lie algebras IV
Yasushi Komori, Kohji Matsumoto, Hirofumi Tsumura
In our previous work, we established the theory of multi-variable Witten zeta-functions, which are called the zeta-functions of root systems. We have already considered the cases o…
On Witten multiple zeta-functions associated with semisimple Lie algebras III
Yasushi Komori, Kohji Matsumoto, Hirofumi Tsumura
We prove certain general forms of functional relations among Witten multiple zeta-functions in several variables (or zeta-functions of root systems). The structural background of t…
