Cyclic sum formulas for multiple zeta and zeta-star values are clean-cut decomposition of each sum formula. The cyclic sum formula for multiple zeta values was conjectured by M. Hoffman and first proved by Y. Ohno, and that for multiple zeta-star values was introduced by Ohno and N. Wakabayashi. In this talk, we present the cyclic sum formulas for finite multiple zeta and zeta-star values, together with our proof for the case of zeta-star. It is a joint work with K. Oyama.
