We give a description of the Whitehead group of a corner skew Laurent polynomial ring A[t+, t-; α] associated with an isomorphism α: A → pAp from a unital associative ring A onto a corner ring pAp. Using this, we compute the Whitehead group of the Leavitt algebras of type (1, n). Copyright © Taylor & Francis, Inc.
