The generalized idempotent conjecture for Abelian graded rings

Let $R=\bigoplus\limits_{n\in G}R_n$ be a ring graded by an Abelian group $G$, and let $H$ be the torsion subgroup of $G$. An idempotent is an element $e$ satisfying $e^2=e$. The second generalized idempotent conjecture. Every idempotent of $R$ is contained in the subring $\bigoplus\limits_{n\in H}R_n$. The paper proves this assertion for commutative graded rings, while the stated general version is not resolved in the supplied text.
