Пример дифференциально простой алгебры Ли, не являющейся свободным модулем над своим центроидом

In this work we construct an example of differentially simple Lie algebra $\Lambda(L(\mathbb{M}))$ over an algebraically closed field of zero characteristic, such that $\Lambda(L(\mathbb{M}))$ is a finitely-generated projective non-free module over its centroid.
