Abstract:
In this talk I will show that if C∗u(X) is a uniform Roe algebra associated to a bounded geometry metric space X, then all bounded derivations from C∗u(X) to itself are inner. We obtain this result using a ``reduction of cocycles" method from Sinclair and Smith. Then the key technical ingredient comes from recent work of Braga and Farah in their paper ``On the Rigidity of Uniform Roe Algebras".
