Let F be a non-archimedean local field. We establish the local Langlands correspondence for all inner forms of the group SL n(F). It takes the form of a bijection between, on the one hand, conjugacy classes of Langlands parameters for SL n(F) enhanced with an irreducible representation of an S-group and, on the other hand, the union of the spaces of irreducible admissible representations of all inner forms of SL n(F) up to equivalence. An analogous result is shown in the archimedean case. For p-adic fields, this is based on the work of Hiraga and Saito. To settle the case where F has positive characteristic, we employ the method of close fields. We prove that this method is compatible with the local Langlands correspondence for inner forms of GL n(F) , when the fields are close enough compared to the depth of the representations.
