Abstract
Using Harish-Chandra parameter space , an explicit formula for the K-theory of the reduced \(C^*\)-algebra of \(\mathrm{GL}(n,{\mathbb {C}})\) is obtained, in analogy with the real case \(\mathrm{GL}(n,{\mathbb {R}})\) [8]. Applying automorphic induction, an instance of Langlands functoriality principle, we then relate the K-theory of \(C_r^*\mathrm{GL}(2n,{\mathbb {R}})\) and \(C_r^*\mathrm{GL}(n,{\mathbb {C}})\).
