Let G be an inner form of a general linear group over a non-archimedean local field. We prove that the local Langlands correspondence for G preserves depths. We also show that the local Langlands correspondence for inner forms of special linear groups preserves the depths of essentially tame Langlands parameters.

The authors wish to thank Vincent Sécherre for some helpful explanations on the construction of simple types for GL m (D), Mark Reeder for pointing out some examples where the depth is not preserved, Wilhelm Zink for explaining properties of the Artin reciprocity map and Paul Broussous for providing the reference [BaBr], which has allowed a substantial simplification of the proof of Proposition 2.6 from a previous version. The second author “Paul Baum” was partially supported by NSF grant DMS-1200475.
