  In the study on multiple zeta values, the duality formula is one of the
families of basic relations and plays an important role in the investigation of
algebraic structure of the space spanned by all multiple zeta values along with
the generalized duality formula (so called Ohno relation) obtained by the
second author. In this article, we will discuss them for the Schur multiple
zeta values which are the values at positive integers of the Schur multiple
zeta function introduced by the first author, O. Phukswan and Y. Yamasaki.
