Abstract

‎Let $\CA$ be an exact category and $\Cb_N(\CA)$ be the category of all $N$-complexes in $\CA$‎. ‎If $\mathbb{X}$ is a sufficiently nice class of objects in $\Cb_N(\CA)$‎, ‎then‎, ‎we give a characterization of elements in the right orthogonal $\mathbb{X}^\perp$ of $\mathbb{X}$ in $\Cb_N(\CA)$ with respect to the induced exact structure‎.‎
