Abstract: Let $\mathbf{A}$ be the adele ring of a number field containing the $n$th roots of unity, and let $\widetilde{\mathrm{GL}}(r,\mathbf{A})$ be an $n$-fold metaplectic covering of $\mathrm{GL}(r,\mathbf{A})$. Under an assumption on $n$, we prove identities between all of the terms in Arthur's invariant trace formulas for $\widetilde{\mathrm{GL}}(r,\mathbf{A})$ and $\mathrm{GL}(r,\mathbf{A})$. We then establish a correspondence between the automorphic representations of these groups.
