\begin{document}$ {\Lambda} $\end{document} hypernuclei corresponding to even–even core nuclei ranging from \begin{document}$ ^8 $\end{document}Be to \begin{document}$ ^{40} $\end{document}Ca with 2, 4, 6, and 8 hyperons are studied using the deformed Skyrme–Hartree–Fock approach. It is found that the deformations are reduced when adding 2 or 8 \begin{document}$ {\Lambda} $\end{document} hyperons, but enhanced when adding 4 or 6 \begin{document}$ {\Lambda} $\end{document} hyperons. These differences are attributed to the fact that \begin{document}$ {\Lambda} $\end{document} hyperons are filled gradually into the three deformed \begin{document}$ p $\end{document} orbits, of which the [110]1/2\begin{document}$ ^- $\end{document} orbit is prolately deformed and the degenerate [101]1/2\begin{document}$ ^- $\end{document} and [101]3/2\begin{document}$ ^- $\end{document} orbits are oblately deformed."> Effects of Λ hyperons on the deformations of even–even nuclei -
