\begin{document}$\rm CP $\end{document} violation in baryon decays, we study the topological amplitudes of bottom baryon decays in the \begin{document}$ S U(3)_{\rm F} $\end{document} limit. The topological diagrams of the charmless two-body decays of bottom baryons are presented in detail. The linear relations between topologies and \begin{document}$ S U(3) $\end{document} irreducible amplitudes are derived through tensor contraction and \begin{document}$ S U(3) $\end{document} decomposition. Four amplitudes among the 13 independent amplitudes are critical to the \begin{document}$\rm CP$\end{document} asymmetries. The small \begin{document}$ \rm CP $\end{document} asymmetries might indicate small relative strong phases between amplitudes \begin{document}$ A_2 $\end{document} and \begin{document}$ A_{12,14}^\prime $\end{document}. To avoid them, we suggest measuring \begin{document}$\rm CP $\end{document} asymmetries in the \begin{document}$ \Xi^0_b\to pK^- $\end{document} and \begin{document}$ \Xi^-_b\to \Lambda^0 K^- $\end{document} decays. Furthermore, the Körner-Pati-Woo theorem can be tested by measuring the branching fractions of the \begin{document}$ \Lambda_b^0\to\Sigma^0K^0_S $\end{document} and \begin{document}$ \Lambda_b^0\to\Sigma^-K^+ $\end{document} modes."> Topological amplitudes of bottom baryon decays in the <i>SU</i>(3)<sub>F</sub> limit -
