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.
